Study Notes
Ingredients in Baking
- Flour is finely ground meal from cereal grains or root crops. It is the primary ingredient in baking
- Wheat flour provides structure, thickening, and nutritive value to baked goods.
- Hard wheat contains more glutenin and gliadin, making stronger flours.
- Strong flours are used in breads and yeast products
- Soft wheat makes weak flours used in cakes, cookies, and pastries.
- North American wheat varieties: hard red winter, hard red spring, hard white, soft white, soft red winter, and durum.
- Bran is the hard outer covering of the kernel, rich in fiber, B vitamins, fat, protein, and minerals.
- Germ is the part of the kernel that can sprout, containing protein, vitamins, minerals, and fat.
- Endosperm is the white, starchy part of the kernel. It remains after bran and germ are removed.
- White flour is composed mainly of starch (68–76%), protein (6–18%), glutenin & gliadin make up 80% of the protein, moisture (11–14%), gums (pentosans 2-3%), fat (1%), ash (mineral content 0.3 to 1.5%), and pigments (carotenoids, orange-yellow).
Types of Flour
- Bread flour: 12–14% protein, high gluten strength, used in breads
- All-purpose flour: mixture of soft and hard flours, 8–11% protein, widely used.
- Cake flour: 7–9% protein, fine texture, high starch content, used in cakes
- Whole wheat flour: contains the whole grain (bran, endosperm, germ). 13% protein
Protein in Flour
- Gluten is a mixture of wheat proteins (glutenin and gliadin), forming a tough, elastic substance when flour is mixed with water.
- Glutenin gives dough strength to hold the leavening gases
- Gliadin provides stretchability to gluten
Hand Test for Flour Strength
- Bakeries typically keep three white flours on hand.
- Bakers can identify flours using sight and touch.
Other Wheat Flours
- Durum flour
- Self-rising flour
- Whole wheat flour
- Bran flour
- Cracked wheat
Other Flours, Meals, and Starches
- Rye, Corn, Spelt, Oats, Buckwheat, Soy, Rice
- Starches: Cornstarch, Waxy maize, and Instant
Sugars
- Sugar is a simple carbohydrate, adding sweetness and flavor.
- Sugar creates tenderness, improves texture, and provides crust color.
- Sugar increases moisture retention.
- Sugar is used as a creaming and foaming agent.
- Sugars provide food for yeast.
- Sucrose (cane or beet sugar)
- Lactose (milk sugar)
- Maltose (malt sugar)
- Fructose (fruit sugar)
- Invert sugar: equal parts of dextrose and levulose, 30% sweeter. Holds moisture, helps cakes stay fresh and resists crystallization.
- Types of granulated sugars: regular granulated sugar, caster sugar, sanding sugar, pearl sugar.
- Other types of sugars include powdered sugar, dehydrated fondant, brown sugar, Demerara sugar
- Non-nutritive sweeteners (sugar substitutes) are available
Syrups
- Syrups are solutions of sugar dissolved in water.
- Simple syrup: dissolved sucrose in water
- Molasses: concentrated sugarcane syrup
- Glucose Corn Syrup: made from cornstarch
- Malt syrup: extracted from barley
- Honey
Fats
- Fats increase tenderness in baked goods by preventing sticking of gluten strands.
- Fats add moistness, richness, and flavor to baked goods.
- Fats assist leavening (as creaming agents) and contribute to flakiness.
- Types of fats: Shortenings (solid fats, usually white and tasteless, devised for handling high-sugar batters), High ratio liquid shortenings, Butter (80% fat, adds flavor and melts at body temperature), Margarine (animal/vegetable fats plus emulsifiers/coloring), Oils (liquid fats), Lard (rendered hog fat).
Advantages of Butter
- Butter has a desirable flavor while shortenings are flavorless.
- Butter melts in the mouth, while shortenings tend to leave a film in the mouth.
Refrigerated Margarine
- Made from various hydrogenated animal and vegetable fats.
- Contains flavoring, emulsifiers, coloring agents.
- Maintains solid form at room temperature.
- Contains fat (80-85%), moisture (10-15%), and other components (salt, milk solids).
Oils
- Oils are liquid fats.
- Oils are not commonly used as shortenings because they spread thoroughly through the dough or batter.
Milk and Milk Products
- Milk and cream increase richness in baked goods.
- They add moisture, enabling gluten development, texture, flavor, and color.
- Milk adds keeping quality and nutritive value.
Eggs
- Eggs contribute structure to baking by emulsifying fats and liquids, aiding leavening, adding moisture, flavor, color, and nutritive value.
- Egg composition: yolk (high in fat and protein, iron, vitamins), white (albumin protein), shell (porous), chalazae (holds yolk), membrane, air cell.
- Market forms of eggs: fresh, frozen, dried
Egg Sizes
- One whole egg = 1.67 oz (47g)
- One egg white = 1 oz(28g)
- One yolk = 0.67 oz (19g)
- 9 1/2 whole eggs = 1 lb
- 16 whites = 1 lb
- 24 yolks = 1lb
Leavening Agents
- Leavening is the incorporation of gases in a baked product.
- This increases volume and forms shape/texture.
Yeasts
- Fermentation by yeast changes sugars to carbon dioxide.
- Yeast is a living organism, vulnerable to temperature changes.
- Temperature affects yeast activity: 34°F is inactive, 60-70°F slow action, 70-90°F best growth, above 100°F reaction slows and above 140°F kills yeast
- Types of yeast: fresh/compressed (preferred by professionals, lasts 2 weeks), active dry, instant dry
Chemical Leaveners
- Baking soda (sodium bicarbonate): releases carbon dioxide gas when moisture and acid are present.
- Baking powder: a mixture of baking soda and acids.
- Double-acting baking powder releases gases with moisture and heat.
- Baking ammonia: a mixture of ammonium carbonate, ammonium bicarbonate, and ammonium carbonate
Air
- Air is incorporated into dough/batter during mixing.
- Air cells are crucial in leavened products made with yeast or baking powder because they collect/hold gases.
Methods of Incorporating Air
- Creaming: beating fat and sugar together to trap air.
- Foaming: beating eggs (with or without sugar) to trap air.
Steam
- Water transforms into steam, expanding to 100 times its volume.
- Moisture in baked goods makes steam a vital leavening agent.
Gelling Agents
- Gelatin: water-soluble protein from animal connective tissue, used as a gelling agent in recipes.
- Two forms of gelatin: powdered and leaf/sheet.
- Gelatin usage in recipes: soaks up 5 times its weight in water, adds to recipes with hot ingredients, and is chilled to set.
- Pectin: vegetable gum, absorbs water, thickens or gels, needs high sugar content and acid for gelling fruit preserves (jams, jellies)
Fruits and Nuts
- Nuts commonly used: almonds, Brazil nuts, cashews, hazelnuts, macadamia nuts, pecans, pine nuts, pistachios, and walnuts.
Nut Products
- Almond paste, Kernel paste, Macaroon paste, Marzipan, Praline paste
Chocolate and Cocoa
- Chocolate and cocoa come from cocoa/cacao beans and are processed (fermented, roasted, ground).
- Cocoa liquor is the dry powder left over after removing cocoa butter.
- Dutch-processed cocoa is processed with alkali which makes it darker and easier to dissolve in liquid.
- Unsweetened chocolate is straight chocolate liquor.
- Sweet chocolate is bitter chocolate with sugar and cocoa butter.
- Milk chocolate is sweet chocolate with milk solids.
- Cocoa butter is the fat pressed from chocolate liquor.
- White chocolate is made of cocoa butter, sugar, and milk solids (no cocoa solids)
- Cocoa absorbs moisture, so flour needs to be reduced by 3/8 of the weight of cocoa added.
Salt, Spices, and Flavorings
- Salt: strengthens gluten, extends gluten's stretchability, and inhibits yeast growth.
- Spices/seeds: Allspice, anise, caraway, cardamom, cinnamon, cloves, ginger, mace, nutmeg, poppy seeds, sesame seeds, zest of lemon/orange.
- Vanilla: often crucial flavoring in pastry shop using vanilla beans and extract.
- Extracts: are flavorful oils/other substances dissolved in alcohol.
- Emulsions: flavorful oils mixed with water using emulsifiers (like vegetable gums)
- Two types of flavorings are present, natural and artificial.
- Alcohols: added for flavor (sweet alcohols/liqueurs-cassis, orange; and non-sweet alcohols-rum, cognac; and wines-Marsala, Madeira).
