Temperatures

Most breads are finished baking at about an internal temperature of 190° to 210°F.

Enriched Breads, breads made with butter, eggs, milk and sugar which are meant to be softer, are done at 190°F.

Sandwich Breads with medium thick crust are done at 205°F .

 

Bread made without eggs and that are not high hydration. Less that 70% water in relation to the weight of a flour

Rustic Breads high hydration breads are done at 210°F

The temperature of  rustic artesian loafs will not get much  above 210°F, because the moisture it contains, even when fully baked, the moisture prevents it from going past the boiling point of water, or 212°F. If you want a hard crunchy dark brown crust and you do not want a gummy interior cook the bread until it reaches 210°F and then cook it for an additional 15 minutes – until it sounds hollow when you tap on it. In most cases bake until the crust is thoroughly browned. For baguettes and rustic breads when you do not want gummy interior but rather are looking for a dryer texture so you want to thoroughly bake your bread because moisture in the interior of an under-baked (light-crusted) baguette will migrate outwards, leaving the crust soft.

 

Rye bread tends towards excessive moistness, and should be baked to an internal temperature of 205°F to 210°F.

 

If you don’t have a thermometer: Take the loaf out of the oven and turn it upside down. Give the bottom of the loaf a firm thump! with your fingers. The bread will sound hollow when it’s done.  If you’re in doubt, it’s better to cook the loaf a little longer than to under cook it.

Quick breads, like banana  zucchini , at 200°F (93°C). At that point, the baking powder/soda will have released its carbon dioxide, the proteins from the eggs will have coagulated and the starches from the flour will have gelled.

     

    Yeast & Sourdough Starter

    1 (7g) pkg of yeast packet is the equivalent of 2 1/4 tsp of yeast. When substituting instant yeast for active dry-you use 25% less, so that would be 1 3/4 tsp instant yeast. You also don’t have to proof instant yeast, mix it in with your dry ingredients.

    A quick rule to adapt recipes to sourdough is: Substitute 1 cup of starter for each package of yeast, and then subtract about 1/2 cup of water and 3/4 cup of flour from the recipe to compensate for the water and flour in the starter.

    You might need to adjust the consistency of the dough — adding or subtracting liquid or flour. Aim for how you know the recipe should look and feel.

     Sourdough needs more rising time than quick yeast. Instead of 1-2 hours, or whatever the original recipe calls for, aim for at least 5 to 8 hours total of rising.

    For a bread using a sourdough starter use 20 to 25 percent of sourdough starter  of the  flour weight (bakers’ percentage).

    Here’s the formula, in bakers’ percentages and weights, using 1 kilo of flour.

    • 100% bread (or all-purpose) flour
    • 70% water
    • 25% young, ripe sourdough starter
    • 2% salt

    And the same in weights, using 1 kilo of flour:

    • 1000g bread (or all-purpose) flour
    • 700g water
    • 250g young, ripe sourdough starter
    • 20g salt

    Baking Terms You Should Know

    • Proofing yeast (rehydrating yeast)  the process of dissolving active dry yeast in warm water to rehydrate.
      • 105°F and 120°F (41°C and 49°C).  is the ideal temperature to rehydrate yeast. Adding a pinch of sugar will help get the yeast started.  But push the water rehydrating temp above 140°F (60°C) and you’ll kill the yeast before it can even wake up.
      • If the yeast is mixed with water below 100°F amino acid will leak into the cell walls and make the dough sticky and hard to handle
    • Autolyse is a period of rest after flour and water are mixed together, and before yeast is added. Enzymes break down the starch in flour into the simple sugars that yeast eats. This step helps flour better absorb water and kick-starts the alignment of gluten and starch.
    • Retarding the dough  refers to chilling dough to slow down yeast activity. Since fermentation will continue during refrigeration, the bread can’t be left at room temperature for too long. If the dough is cool and the fermentation sluggish, the bread can receive upwards of 1 hour of floor time before retarding. If your kitchen is hot, , the bread might be better if the loaves are retarded as soon as they are formed. Experience will be the best guide.  For breads that retard for up to about 8 hours, a temperature of about 50°F should is good.  Dough retarding for 16 hours needs a temperature closer to 40°F  After 22 to 24 hours of refrigeration, dough begins to become quite acidic.
    • Bulk fermentation  is the dough’s first resting period after yeast has been added, and before shaping. Total bulk fermentation time is usually 2 to 5 hours depending on the temperature. Bulk fermentation is complete when the dough has doubled in size and you can stick two fingers in the risen dough, up to the second knuckle, and then take them out and the indentations remain in the dough. This means the dough it is ready for punch down. If  the indendations do not remain, cover and let the dough rise longer.

    Proofing the Dough

    Proofing is a step in the preparation of yeast bread and other baked goods where the dough is allowed to rest and rise a final time after bulk fermetation and shaping, just before baking.

    Over proofing When carbon dioxide exerts more pressure than a fully proofed dough can withstand, the cell membranes tear, releasing the gas and deflating the dough. An over proofed dough won’t expand much during baking. Over proofed doughs collapse due to a weakened gluten structure and excessive gas production

    Under proofing happens when the dough has not had enough time to create carbon dioxide.  To check, gently stick two fingers in the risen dough up to the second knuckle and then take them out. If the indentations remain the dough is “ripe” and ready for punch down. If not, cover and let the dough rise longer.

    A proofing box is a warm area (75-105°F) designed to maximize proofing by keeping dough warm and humid.

    You can make your own proofing box by placing a pan at the bottom of the oven with a pot with about a gallon boiling water ono the pan. Place the covered bread on the rack above, and keep the oven door closed. It’s a good idea to use a thermometer to be sure the temperature is staying between 80 and 95°F

    Another way to create a proof box is to heat the oven at the lowest setting for one or two minutes, then TURN IT OFF. In other gas ovens, the pilot light will provide enough warmth, so you don’t need to turn it on at all. The oven temperature should not exceed 90°F during the rising time. Place a pan of very warm water toward the back of the oven to provide moisture, which keeps the dough soft during rising. Place the covered bowl or pan of dough on the center rack and close the door. Ideal rise temperatures are between 80°F – 90°F; higher temperatures may kill the yeast and keep the dough from rising; lower temperatures will slow the yeast activity which will increase your rise time.

    Proofing basket, also called a banneton, is a basket made of cane,  or other materials that helps bread loaves keep their shape during proofing.

    How Temperature effects rising time

    Tips for Successful Proofing

     

    • Use proofing containers that allow dough room to rise. They should be about three times the size of the dough.
    • If dough gets too warm during the bulk fermentation, the yeast will expand more quickly than the gluten structure. The gluten structure won’t be able to keep up with fermentation and air bubbles will collapse on themselves. Do not proof dough above 110°F. If yeast gets too cold (40°F or below), it will go dormant.
    • If you want to proof the dough slower consider retarding dough by proofing it at a colder temperature (around 50°F), which will slow down the rise and help develop flavors.
    • Cover dough with a plastic bag or cloth during proofing to prevent the dough from drying out or forming a skin
    • A few degrees difference in dough temperature can change the duration of the bulk fermentation or the final proofing significantly. When baking bread with regular active dried yeast, the optimum (for speed alone) temperature is just over 27ºC/80ºF.
    •  The bacterial activity peaks at 93°F, so some bakers choose to ferment at 90°F to get a more sour bread. At 70°F the activity of the yeast has roughly halved, so the fermentation will take twice as long.
    •  Use warm water in the winter to get the dough to the right temperature.

    High Hydration Doughs

     

    Wetter dough is harder to handle

    • The dough will be more slack, so it’ll be harder to shape. (In addition, extra steps may be needed to develop enough dough strength so that it can rise well).
    • Texture – The higher the hydration level of your bread, the more open the crumb will be (i.e. bigger holes inside).
    • Appearance – The higher the hydration of your loaf, the less amount it is likely to rise because the dough is more slack.

     

    Tips & Tricks

    Autolyse – To Autolyse, is to mix the flour and water of a recipe, and lett it sit for a period of time before adding the starter and salt. Autolyse is not an absolutely necessary step, but once your dough gets to a higher hydration level, having a longer autolyse can be the difference between a dough being managable or too difficult to handle.

    Retard the Dough to Make it Easier to Handle – ‘Retarding’ the dough by putting it in the fridge will help stiffen it slightly, making it easier to work with. You can retard it during the last part (or all) of the bulk ferment stage in order to make it easier to handle and shape. You can also retard the dough during it’s second rise. This will help to hold its shape better when turning it out of the proofing basket.

    Flour your Proofing Basket Well to Avoid the Dough Sticking – To prevent the wet high-hyrdation dough from sticking to the proofing basket, flour the basket well before placing the dough inside.  Using a coarse grain, such as dark rye or whole grain is my preference, but many bakers use rice flour because as it is quite good at preventing sticking.

    Use Wet Hands When Handling Dough – Using wet hands when handling the dough will prevent the dough from sticking to your hands.

    Uncover the Dough Halfway through Baking – Higher hydration dough will produce a thinner crust when in the oven. To make it nice and crispy, remove its cover or steam source halfway through the bake to ensure it crisps up nicely.

    Pre-Shape the Dough to Help a Slack Dough  – Pre-shaping is not necessary at all for lower hydration dough. A wet, slack dough will benefit from a pre-shape before its final shape. It will help to further develop structure in the loaf and help it to stand taller. Leave 20 minutes to one hour in between the pre-shape and final shaping for the dough relax. Pre-shaping will make the final shaping significantly easier!

    Chart of waters effect on dough

    Water & Steam

    It is in the presence of water that gluten forms.

    Water helps  disperse salt, sugar, and yeast.

    Water is necessary for yeast fermentation and reproduction; softer doughs will ferment more quickly than dry doughs.

    Water is responsible for the consistency of bread dough.

    The temperature of water can be adjusted in order to bring your dough to the correct temperature.

     

    pH of Water

    The amount of acidity, expressed as pH has an effect on fermentation. Hard water is more alkaline than soft water, and can decrease the activity of yeast. Yeast prefers slightly acid conditions to work best.  Bread doughs are generally in the region of pH 5.0 to 6.0

     

    In cases where the acid leavener does not neutralize the sodium bicarbonate (baking soda), then the excess bicarbonate will increase the degree of browning of the sugars during baking. Maillard browning increases at higher pH values (>8.0). To prevent this, additional acid, e.g., cream of tartar (potassium bitartrate) is added to lower the pH and neutralize remaining baking soda

     

    Steam

    The other way in which water effects bread is in the form of steam that is put into the oven at the beginning  of baking. It helps develop  color to the crust and a surface shine on the loaf, and also increases the volume of the bread.

    Crust color is enhanced when steam is injected into the oven. This is because at the early stages of baking, there is a rapid increase in enzymatic activity on the surface of a loaf. These enzymes break down the starches in the dough into sugar-like compounds and other simple sugars called reducing sugars. Steaming the oven has a cooling effect on the dough, and this enables the enzymes to remain active for a longer period of time. This in turn contributes to crust browning through the Maillard reaction, and later through caramelization of the crust.

    A properly steamed oven promotes a crust with a good sheen to it. This is because steam at the initial stages of baking provides moisture that gelatinizes the starches on the surface of the loaf. The starches swell and become glossy, giving us a shining crust.

    A properly steamed oven results in bread with better volume. When dough is put into an oven without steam, the surface of the loaf quickly heats up and a crust forms on the surface, oven spring is reduced, and the bread’s ability to attain further volume is impeded. On the other hand, in a steamed oven, the surface of the dough remains moist longer, enabling greater oven spring to occur before the formation of a surface crust, and the result is bread with superior volume.

    The benefits of steam occur only during the first third or so of the baking cycle.  In order to ensure that the crust remains thin and crisp, it is important to finish the bake in a dry oven. For this reason, the oven door should  partially open for the last portion of the bake.

    Adding Fat

    Besides flavor, fat affects the texture of the finished bread. The fat coats the gluten strands and makes the finished product more tender – both the crumb and crust – and it makes the crumb more fine grained, or cake like. It also makes the loaf seem moister. Breads that are made with fat in them don’t dry out as quickly, so the shelf life is improved.

     

    When you add the fat to the dough also makes a difference. You will get better gluten development if the fat is added after the gluten has been developed; rather than if you try to knead a dough that has the fat already incorporated.

     

    A dough with a lot of fat can take much longer to rise, and that issue is complicated by the fact that many fat-laden breads also have a lot of sugar. The excess sugar also retards the rise.

     

    For brioche-like breads with a lot of butter in them, you can manipulate the texture of the resulting bread by changing when the butter is added. If the fat is added at the beginning, before the dough has been kneaded, the texture will be more cake-like. If the gluten is allowed to develop before the butter is added, the texture will be more bread-like.

    Eggs

    Sometimes eggs are added as a part of the liquid.

    Eggs add richness, tenderness and color, as well as nutrients.

     

     

     

    Temperature Stages of Baking:

    80°–170°F (27°–77°C) Gasses are formed and trapped More CO2 from yeast is produced, as are gasses from any chemical leaveners and alcohol vapor from the fermentation
    140°–212°F (60°–100°C) Starches gelatinize Starch granules swell and burst, creating a thick web of starch molecules
    160°–185°F (71°–85°C) Proteins coagulate The gluten strands curl up, tightening their links with each other, and solidifying the bread’s structure
    212°F (100°C) (adjusted for elevation) Water boils Steam is one of the most important leaveners in bread
    320°F (160°C) and up Sugars caramelize, Maillard reaction Sugars on the exterior will brown at this temperature and others will combine with proteins to produce nutty, toasty flavors and beautiful color
    Carryover baking After the bread is removed from the oven, the temperatures will equalize, with the interior continuing to warm as the exterior begins to cool
