Study Notes
What is Sourdough Bread?
- Sourdough bread is created through natural fermentation using wild yeast and lactic acid bacteria, giving it a tangy flavor and chewy texture.
- Sourdough is made with a "starter," which is a mixture of flour and water containing wild yeast and bacteria.
Health Benefits of Sourdough
- Sourdough is easier to digest because the fermentation process breaks down gluten and starches.
- Sourdough has fewer preservatives due to its natural acidity, which inhibits the growth of mold and harmful bacteria.
- Sourdough is rich in probiotics because the fermentation process introduces beneficial bacteria that support gut health and improve digestion.
History of Sourdough
- Sourdough is one of the oldest forms of leavened bread, dating back over 5000 years to ancient Egypt.
- It is believed that sourdough was discovered accidentally when wild yeast fermented dough left out in the open.
- Sourdough traveled to Greece and Rome, appearing in 17th-century French cookbooks.
- The French brought sourdough to the Americas, where it became a staple during the California gold rush in 1849.
- Sourdough remains popular in San Francisco today.
The Science of Sourdough
- Microorganisms in sourdough starter feed on carbohydrates in flour, producing carbon dioxide that causes the dough to rise.
- Lactic acid bacteria in sourdough produce acids that give the bread its tangy flavor and contribute to its long shelf life.
- The slow fermentation process breaks down proteins and starches in the dough.
Sourdough Ingredients
- Flour provides food for the wild yeast and bacteria. High-protein flours like bread flour help create a strong gluten network for a chewy texture.
- Water activates the yeast and bacteria, kickstarting fermentation. It also helps form gluten, which creates the structure of the dough.
- Salt adds flavor and controls fermentation by slowing yeast activity. It also strengthens gluten, improving dough texture.
- Sourdough starter is a mixture of flour and water containing wild yeast and lactic acid bacteria. It ferments the dough, giving it its characteristic tangy flavor.
Making the Starter
- Day 1: Combine ½ cup of flour (whole wheat or all-purpose) with ½ cup of water in a clean jar or bowl, stir well, cover loosely, and leave at room temperature for 24 hours.
- Day 2-5: Discard half of the starter each day and add ½ cup of fresh flour and ½ cup of water. Stir, cover loosely, and repeat for 4-5 days until the starter becomes bubbly and begins to smell tangy.
- Day 6: The starter is ready when it doubles in size within a few hours after feeding, with a pleasant, slightly sour aroma. Store it in the refrigerator and feed it weekly to maintain.
Scoring Sourdough Bread
- Scoring refers to making shallow cuts on the surface of the dough just before baking.
- The cuts allow the bread to expand in a controlled manner during baking, creating an attractive appearance and preventing the bread from bursting unpredictably.
Basic Scoring Techniques
- Single Slash: A simple, long cut down the center, perfect for beginners.
- Cross Slash: Two intersecting slashes forming an “X.”
- Decorative Patterns: For more advanced bakers, intricate designs like leaves, spirals, or wheat stalks can be created.
Tips for Successful Scoring
- Use a sharp blade or bread lame for clean cuts.
- Score at a 30-45 degree angle to allow better expansion.
- Score quickly and confidently to avoid dragging or tearing the dough.
Sourdough Around the World
- France: Pain de Campagne, also known as French country bread, is a rustic sourdough often made with a blend of white, whole wheat, and rye flours. It has a mild, nutty flavor and a chewy crust.
- Germany: Pumpernickel is a dark, dense sourdough bread made from coarsely ground rye flour.
What is a Quick Bread?
- Quick breads use chemical leavening agents to rise
- Examples of Quick Breads: muffins, biscuits, scones, pancakes, waffles and banana, pumpkin, zucchini bread
Chemical Leavening Agents
- Produce carbon dioxide gas
- Cause baked goods to rise
- Examples of chemical leavening agents: Baking Soda, Baking Powder
Baking Powder vs. Baking Soda
- Baking powder has baking soda and an acid
- Baking soda requires an acid to activate the chemical reaction
Quick Bread Mixing Methods
- The method for mixing quick bread depends on the temperature of the fat
Creaming Method
- Fat should be soft at room temperature
- Fat and sugar are creamed together
- Add eggs and liquids after creaming fat and sugar
- Then add dry ingredients
- Examples: Some muffins
Biscuit Method
- Fat should be solid and chilled
- Fat is cut into the dry ingredients
- The larger the pieces of fat, the flakier the pastry will be
- Then liquids are added
- The dough is lightly stirred
- Examples: Scones, biscuits
Muffin Method
- Fat should be liquid, like oil or melted butter
- Liquid ingredients are added to dry ingredients
- Fold ingredients together gently
- Batter should appear lumpy
- Examples: Pancakes, waffles, and some muffins
Overmixing
- The most common mistake when making quick breads: overmixing
- Overmixing leads to tunneling
- Tunneling is large holes in muffins and cakes caused by overmixing
- Properly mixed muffins will rise evenly and be soft and delicate
- Properly mixed muffins will not have large irregular holes, will not be tough or chewy, and will not show signs of tunneling
Quick Breads
- Quick bread relies on chemical leavening agents to rise.
- Quick bread examples include muffins, biscuits, scones, pancakes, waffles, banana bread, pumpkin bread, and zucchini bread.
- Chemical leavening agents produce carbon dioxide gas, which makes baked goods rise.
- Chemical leavening agents produce carbon dioxide gas through a chemical reaction when moisture and/or heat are added.
- Examples of chemical leavening agents include baking soda and baking powder.
Quick Bread Mixing Methods
- Quick bread mixing methods depend on the temperature of the fat used.
Creaming Method
- The creaming method uses soft, room-temperature fat.
- The creaming method entails beating softened fat and sugar together until smooth to incorporate air.
- After creaming fat and sugar, add the eggs and other liquids.
- Then add the dry ingredients.
- Examples of quick breads using the creaming method include some muffins.
Biscuit Method
- The biscuit method uses solid, chilled fat.
- The biscuit method involves cutting fat into dry ingredients.
- The size of the fat pieces affects the flakiness of the pastry.
- Liquids are added after cutting in fat.
- The dough is lightly stirred to combine.
- Examples of quick bread using the biscuit method include scones and biscuits.
Muffin Method
- The muffin method uses liquid fat, like oil or melted butter.
- The muffin method uses liquid ingredients added to dry ingredients.
- The ingredients are gently folded together.
- The batter should appear lumpy.
- Overmixing the batter creates a smooth batter and results in tunneling in the baked goods.
- Examples of quick bread using the muffin method include pancakes, waffles, and some muffins.
Over Mixing
- Over-mixing quick bread is the most common mistake.
- Over-mixing leads to tough, chewy baked goods.
- Proper mixing results in soft, delicate baked goods.
- Over-mixing results in tunneling, large holes in baked goods, specifically muffins and cakes.
- Over-mixing can be identified by uneven rising and tough, chewy baked goods.
- Proper mixing can be identified by even rising, soft, delicate baked goods, and an absence of tunneling.
