Study Notes

Flour

Flour is the primary structural component in baked goods.
Flour contains protein which forms gluten when mixed with water.
Gluten stretches to contain expanding leavening gases during rising, resulting in a light and airy product.
Hard wheat flour (high protein) is ideal for yeast breads, but can make cakes, quick breads, and pastries tough.
Soft wheat flour (low protein) is better suited for cakes, quick breads and pastries.
Bread flour is a hard wheat flour with about 12% protein, resulting in a strong gluten framework and a light, high volume loaf.
Oat flour can be substituted for up to 1/3 of wheat flour in bread.
Cornmeal and corn flour contain 7-8% protein and do not form gluten.
Rice flour contains 6.5-7% protein and does not form gluten, making it a suitable alternative for those with gluten intolerance.
Potato starch flour is typically used in combination with other flours, offering a mild potato taste.
Soy flour is high in protein (50%) but does not form gluten. It can be used to boost protein in baked goods, but excessive use can impact flavor and cause rapid browning.

Sweeteners

Sucrose (table sugar) plays a role in yeast activity, dough tenderization, and browning.
Fructose is sweeter than sucrose and attracts more water, leading to moist baked goods.
Honey is sweeter than sugar due to its fructose content, contributing a distinct flavor and moisture.
Molasses imparts a dark color and strong flavor. It is less sweet than sugar and can cause browning and requires baking soda to counteract its acidity.
Artificial sweeteners provide sweetness but lack the browning, tenderizing, and moisture retaining properties of sugar. Specific recipes are often needed for optimal results.

Salt

Salt enhances flavor and sweetness in baked goods.
In yeast dough, salt slows down fermentation, preventing overly rapid rising and affecting bread shape and flavor.

Leavening Agents

Baking soda produces gas when combined with acidic ingredients like vinegar, lemon juice, or molasses.
Baking powder contains baking soda and acid, producing two rising stages: one during mixing and another during baking.
Yeast is a living organism that produces carbon dioxide gas during fermentation, causing dough to rise.

Fats

Fats contribute tenderness, moistness, and a smooth mouthfeel to baked goods.
Fats enhance the flavors of other ingredients.
Reducing fat in muffins can result in a tougher product due to increased gluten development.
Shortening is 100% fat and contributes to flakiness in pastries.
Butter imparts flavor and melts at body temperature, providing a pleasant mouthfeel.
Margarine is made from hydrogenated fat or oil and can be used interchangeably with butter.
Reduced-fat substitutes have less than 80% fat and may require adjusted recipes.
Fat-free margarines are best used as spreads.
Oil can be used in some recipes, but tends to produce a mealy rather than flaky texture.

Eggs

Eggs contribute flavor, color, structure, air incorporation, liquid, fat, protein, and emulsification.
Reducing yolks can decrease tenderness.
Reducing whites can reduce volume.
Egg yolks are essential for emulsion, ensuring uniform flavor and texture.
For low-fat alternatives, use 2 egg whites for 1 whole egg.

Liquids

Liquids are crucial for hydrating proteins, starch, and leavening agents.
Liquids contribute moistness and improve texture.
Water vaporization during baking expands air cells, increasing volume.
Milk provides water, nutrients, flavor, and browning.
Scalding milk before adding to yeast dough improves quality and bread volume.
Fruit juices are acidic and best used in recipes containing baking soda.
