How to understand the fundamentals of baking science and how they apply to french patisserie


Baking is often considered both an art and a science. It requires creativity, precision, and a good understanding of how ingredients interact with each other and with heat. This is especially true for French patisserie, which is known for its elegance, complexity, and variety of desserts. From flaky croissants to delicate macarons, French patisserie requires a high level of skill and knowledge to master.


But what are the fundamentals of baking science and how do they apply to French patisserie? In this blog post, we will explore some of the key concepts and principles that every baker should know, and how they can help you create beautiful and delicious French pastries.


The Role of Ingredients


One of the most important aspects of baking science is understanding the role of each ingredient in a recipe. Different ingredients have different functions and properties that affect the texture, flavor, structure, and appearance of the final product. Here are some of the main ingredients used in baking and their roles:


- Flour: Flour is the main ingredient in most baked goods, providing structure, strength, and elasticity. Flour contains two proteins, glutenin and gliadin, that form gluten when mixed with water. Gluten is responsible for giving dough its stretchiness and ability to trap air bubbles. The type and amount of flour used in a recipe can affect the density, tenderness, and crumb of the baked good. For example, bread flour has a high protein content and forms a strong gluten network, resulting in a chewy and airy bread. Cake flour has a low protein content and forms a weak gluten network, resulting in a soft and fine cake.


- Sugar: Sugar is not only a sweetener, but also a tenderizer, humectant, leavener, and flavor enhancer. Sugar helps tenderize baked goods by weakening the gluten network and preventing it from overdeveloping. Sugar also attracts moisture and helps keep baked goods moist and soft. Sugar can also act as a leavener by creating air bubbles when creamed with butter or whipped with eggs. Sugar also enhances the flavor of baked goods by caramelizing when heated and creating complex aromas. The type and amount of sugar used in a recipe can affect the sweetness, color, texture, and shelf life of the baked good. For example, granulated sugar is commonly used for cookies and cakes because it dissolves easily and creates a fine crumb. Powdered sugar is often used for icings and glazes because it dissolves quickly and creates a smooth consistency.


- Butter: Butter is a fat that adds richness, flavor, moisture, tenderness, and flakiness to baked goods. Butter helps create tenderness by coating the flour particles and preventing them from forming too much gluten. Butter also helps create flakiness by creating layers of fat between layers of dough, which separate when baked and create air pockets. Butter also adds flavor by browning when heated and releasing buttery aromas. The type and amount of butter used in a recipe can affect the richness, flavor, and texture of the baked good. For example, unsalted butter is commonly used for baking because it has a neutral flavor and a high fat content. Salted butter can be used for some recipes, but it may affect the salt balance and flavor of the baked good. Margarine or vegetable oil can be used as substitutes for butter, but they may have different melting points and water contents that can affect the outcome. - Eggs: Eggs are a versatile ingredient that add moisture, richness, flavor, color, and structure to baked goods. Eggs help bind ingredients together and create emulsions that prevent separation. Eggs also act as leavening agents by trapping air when whipped or beaten. Eggs also contribute to browning and flavor development by undergoing Maillard reactions when heated. The type and amount of eggs used in a recipe can affect the density, tenderness, and volume of the baked good. For example, whole eggs add more moisture and richness than egg whites, which add more lightness and airiness. Egg yolks add more fat and emulsifying power than egg whites, which add more protein and structure.

- Milk or Cream: Milk or cream add moisture, richness, flavor, and color to baked goods. Milk or cream help dissolve sugar and salt and create a smooth batter or dough. Milk or cream also contribute to browning and flavor development by undergoing Maillard reactions when heated. The type and amount of milk or cream used in a recipe can affect the tenderness, crumb, and crust of the baked good. For example, whole milk adds more fat and richness than skim milk, which adds more water and lightness. Heavy cream adds more fat and moisture than light cream, which adds more water and airiness. - Leavening Agents: Leavening agents are substances that produce gas that makes baked goods rise and expand. Leavening agents can be biological, chemical, or physical. Biological leavening agents are living organisms that produce carbon dioxide through fermentation, such as yeast or sourdough starter. Chemical leavening agents are compounds that react with each other or with other ingredients to produce carbon dioxide, such as baking soda or baking powder. Physical leavening agents are methods that incorporate air into the batter or dough through mechanical means, such as whipping, beating, creaming, or folding. The type and amount of leavening agents used in a recipe can affect the texture, flavor, shape, and volume of the baked good. For example, yeast produces a slow and steady rise that creates a chewy and flavorful bread. Baking powder produces a fast and strong rise that creates a light and fluffy cake. Whipping produces a light and airy rise that creates a delicate and fine meringue.

- Salt: Salt is a seasoning that enhances the flavor of baked goods by balancing the sweetness and bringing out other flavors. Salt also strengthens the gluten network by tightening it and preventing it from overstretching. Salt also helps control the growth of yeast by inhibiting its activity. The type and amount of salt used in a recipe can affect the flavor, texture, structure, and shelf life of the baked good. For example, table salt has a fine grain and dissolves easily in batters or doughs. Kosher salt has a coarse grain and adds more texture to crusts or toppings. Sea salt has a natural flavor and adds more complexity to sweet or savory baked goods. The Role of Techniques Another important aspect of baking science is understanding the role of different techniques in creating different effects in baked goods. Different techniques involve different ways of mixing, shaping, and baking the ingredients to create different effects in baked goods. Different techniques involve different ways of mixing, shaping, and baking the ingredients to create different effects in baked goods. Here are some of the main techniques used in baking and their roles: - Creaming: Creaming is a technique that involves beating butter and sugar together until light and fluffy. This technique helps incorporate air into the batter and creates a fine and tender crumb. Creaming is commonly used for cakes, cookies, and muffins.

- Whipping: Whipping is a technique that involves beating air into a liquid or semi-liquid ingredient, such as egg whites, cream, or custard. This technique helps create a light and airy texture and increases the volume of the ingredient. Whipping is commonly used for meringues, whipped cream, soufflés, and mousses.

- Folding: Folding is a technique that involves gently combining a light and airy ingredient with a heavier one, such as whipped egg whites with cake batter or whipped cream with fruit puree. This technique helps preserve the air bubbles in the light ingredient and prevents deflation. Folding is commonly used for sponge cakes, chiffon cakes, angel food cakes, and mousses.

- Laminating: Laminating is a technique that involves creating thin layers of dough separated by thin layers of butter or other fat. This technique helps create a flaky and crisp texture and creates air pockets that expand when baked. Laminating is commonly used for puff pastry, croissants, danishes, and palmiers.

- Blind Baking: Blind baking is a technique that involves partially or fully baking a pie or tart crust before adding the filling. This technique helps prevent the crust from becoming soggy or undercooked by the moisture from the filling. Blind baking is commonly used for custard pies, fruit tarts, quiches, and lemon meringue pies. The Role of Temperature Another important aspect of baking science is understanding the role of temperature in affecting the outcome of baked goods. Temperature can affect both the preparation and the baking of the ingredients, as well as the storage and serving of the finished product. Here are some of the main factors that temperature can influence in baking: - Gluten Development: Gluten development is affected by temperature in two ways. First, cold temperatures slow down gluten development by reducing the activity of enzymes that break down starch into sugar. This results in less sugar available for yeast fermentation and less gas production. Cold temperatures also make gluten more elastic and less extensible, which makes it harder to stretch and shape. Second, warm temperatures speed up gluten development by increasing the activity of enzymes that break down starch into sugar. This results in more sugar available for yeast fermentation and more gas production. Warm temperatures also make gluten more extensible and less elastic, which makes it easier to stretch and shape.

- Leavening: Leavening is also affected by temperature in two ways. First, cold temperatures slow down leavening by reducing the activity of yeast or bacteria that produce carbon dioxide through fermentation. This results in less gas production and less rise. Cold temperatures also make butter or other fats more solid, which helps trap air bubbles in dough or batter and create flakiness or lightness. Second, warm temperatures speed up leavening by increasing the activity of yeast or bacteria that produce carbon dioxide through fermentation. This results in more gas production and more rise. Warm temperatures also make butter or other fats more soft or liquid, which helps spread the dough or batter and create thinness or crispiness. - Browning: Browning is a process that occurs when baked goods are exposed to high temperatures and develop a golden crust and a complex flavor. Browning is caused by two main reactions: caramelization and Maillard reaction. Caramelization is the breakdown of sugar molecules into smaller molecules that have a brown color and a sweet and nutty flavor. Maillard reaction is the combination of sugar and protein molecules that have a brown color and a savory and roasted flavor. Both reactions are influenced by temperature, time, moisture, pH, and type of ingredients. The Role of Time Another important aspect of baking science is understanding the role of time in affecting the outcome of baked goods. Time can affect both the preparation and the baking of the ingredients, as well as the storage and serving of the finished product. Here are some of the main factors that time can influence in baking: - Resting: Resting is a technique that involves letting the dough or batter sit for a certain period of time before shaping or baking. Resting helps relax the gluten network and redistribute the moisture in the dough or batter. Resting also helps improve the flavor and texture of the baked good by allowing fermentation or other chemical reactions to take place. Resting is commonly used for breads, pies, cookies, and cakes.

- Proofing: Proofing is a technique that involves letting the dough rise for a certain period of time before baking. Proofing helps increase the volume and lightness of the baked good by allowing yeast or bacteria to produce carbon dioxide gas through fermentation. Proofing also helps develop the flavor and texture of the baked good by creating air pockets and gluten strands in the dough. Proofing is commonly used for breads, croissants, danishes, and brioche.

- Baking: Baking is a technique that involves exposing the dough or batter to high temperatures for a certain period of time to cook it. Baking helps set the structure and shape of the baked good by solidifying the starch and protein molecules in the flour. Baking also helps create browning, flavor development, and crust formation by causing caramelization and Maillard reaction on the surface of the baked good. Baking time depends on several factors, such as oven temperature, size and shape of the baked good, type and amount of ingredients, and desired doneness.

- Cooling: Cooling is a technique that involves letting the baked good cool down for a certain period of time after baking. Cooling helps stabilize the structure and shape of the baked good by allowing it to contract and firm up. Cooling also helps preserve the moisture and freshness of the baked good by preventing evaporation and condensation. Cooling time depends on several factors, such as size and shape of the baked good, such as a cake or a pie, and the type of container or wrap used to cover it, such as a cake dome or a foil. Generally, it is best to let the baked good cool completely on a wire rack before storing or serving it. - Storing: Storing is a technique that involves keeping the baked good in a suitable place and condition for a certain period of time before serving or consuming it. Storing helps preserve the quality and freshness of the baked good by preventing spoilage, staling, drying, or molding. Storing depends on several factors, such as the type and amount of ingredients, the type and amount of leavening agents, the type and amount of frosting or filling, and the ambient temperature and humidity. Generally, it is best to store baked goods in an airtight container or wrap in a cool and dry place. Some baked goods may require refrigeration or freezing for longer shelf life or better texture.
