Overview of the history and significance of baking, basic baking principles, and the importance of using proper tools and techniques.
Introduction to Baking – Study Notes
| Principle | What Happens | Why It Matters |
|---|---|---|
| Heat Transfer | Conduction (from metal pan) → Convection (air circulation) → Radiation (oven walls) | Determines how quickly the batter cooks and how evenly it rises. |
| Moisture Management | Water evaporates, creates steam, and later sets the crumb. | Controls crumb softness, crust formation, and shelf‑life. |
| Leavening | Gas (CO₂, steam) expands the batter. | Gives rise, lightness, and texture. |
| Protein & Starch Gelatinization | Gluten (flour) coagulates; starches absorb water and swell. | Sets the structure so the product holds its shape after cooling. |
| Maillard Reaction & Caramelization | Browning of sugars & amino acids at >300 °F (150 °C). | Produces flavor, aroma, and attractive color. |
| Ingredient | Primary Function | Typical Ratios (per 1 lb/450 g flour) |
|---|---|---|
| Flour | Structure (gluten) & bulk | 100 % |
| Water / Milk | Hydration, dissolves ingredients, steam source | 60‑70 % |
| Sugar | Sweetness, tenderizing, browning, yeast food | 5‑15 % |
| Fat (butter, oil, shortening) | Tenderness, flavor, aeration, crust softness | 5‑15 % |
| Eggs | Emulsify, leaven, add color & richness | 5‑10 % |
| Leavening Agents | Produce gas for rise | Yeast: 1‑2 % (by flour weight) Baking powder/soda: 1‑2 % |
| Salt | Flavor enhancer, strengthens gluten | 1‑2 % |
| Add‑ins (nuts, fruit, spices) | Flavor & texture | Variable |
Percentages are expressed as baker’s percentage (ingredient weight ÷ flour weight × 100).
| Technique | Description | Typical Uses |
|---|---|---|
| Creaming | Beat butter + sugar until light & fluffy; incorporates air. | Cakes, cookies |
| Meringue | Whip egg whites with sugar to form a stable foam. | Angel food cake, pavlova |
| Kneading | Work dough to develop gluten network. | Bread, pizza dough |
| Folding | Gently incorporate light ingredients (e.g., whipped egg whites) without deflating. | Soufflés, chiffon cakes |
| Proofing | Allow yeast dough to rise in a warm, humid environment. | Breads, rolls |
| Blind Baking | Bake a crust without filling (often with weights). | Pies, tart shells |
| Glazing / Egg Wash | Brush with liquid (egg, milk, sugar syrup) before baking for shine & color. | Pastries, breads |
