There are many complex proteins in eggs, which undergo transformations when they are beaten, heated, or otherwise manipulated in some way. Eggs are the real multi-tasker of the group, providing functions similar to each of the other ingredients here, along with some unique to themselves. Wheat flour is about 75% starch and 6-13% protein, depending on how it is processed. Egg whites alone can be manipulated in many ways to create quite complex structures and effects in different baked goods. This allows it to be used directly in cakes without the addition of salt or a leavening agent.

Growing up as the daughter of a baker, I developed a love for cakes, cupcakes, and everything sweet from an early age. Egg whites create structure, offering stability, aeration and consequently volume. This does not cost you anything extra. This moderating effect is important in bread baking as it prevents the dough from rising too quickly, and allows other fermentation reactions to occur, building more complex flavors.
The reaction occurs as soon as the baking soda comes into contact with liquid, and so it is important to bake it as soon as possible after mixing to contain as much of the gas as possible in the batter. Liquid also plays an additional role in the rising of baked goods, as the water turns to steam in the oven. This gives a lighter and airier texture to the cake. You can’t have a non elastic filo dough. Spread the icing over the top of the jam, and then carefully place the other cake on top.
Gliadin and Glutenin are only produced by cereal plants, with wheat containing the highest levels of these proteins when compared to other cereal grains, i.e. Gluten is present in these products; however unlike for bread, the development of gluten is usually discouraged as it can result in an undesirable and tough texture in these products. Without gluten, cakes are drier, crumbly and have a shorter shelf life but there are a number of ways you can use to try and counter this. It also provides nutritive value in the form of protein and fat, and assists in the browning of crusts. Cake and pastry flour is therefore mixed to have a much lower protein content, of around 7.5%. Find out more about xanthan gum. It is the substance of the cake or loaf, providing texture and nutritional content. Baking powder is essentially a more convenient form of baking soda and is often used in quick breads. Icing sugar and pearl sugar can be dusted or sprinkled over baked cakes and pastries to produce a pleasing effect, or icing sugar can be mixed with water to create icing or frosting. These agents can be natural, living organisms, or synthesized chemicals. These, along with the process of caramelization, produce many different organic molecules that, when combined, produce the wonderful flavors that are found in bread and pastry crusts, as well as their brown color. The amount of protein contained in flour and the extent to which it is allowed to develop are important factors in the final texture of the baked good. You may not have thought of it this way before, but baking is really a type of chemistry experiment – albeit a tasty and useful one which you perform in your kitchen instead of a lab. It can be found in dried and fresh forms, with the dried form lasting much longer than the fresh. A very high protein bread flour, such as Canadian Manitoba Cream, will give the greatest volume to a loaf, whereas a lower protein bread flour will produce bread with a distinctly European character, such as an Italian ciabatta or a French pain de campagne. The speed of yeast fermentation can be controlled by the addition of salt and sugar. It gives cakes their structure and moist texture. Chocolate brownies are a popular treat and can be easily adapted to be gluten free. The carbon dioxide is caught in the gluten structure of the dough, giving it volume, and contributing to its texture. Sugar also holds moisture in the finished product. Then add in the vanilla essence. It also helps to soften the crumb, however too much will negatively affect the gluten development. Here follows then an overview of the functions of the most popular ingredients in baking bread, cakes and pastry. Now that you have a solid grasp on the fundamentals, find out which tools you need to take your baking to the next level. Do grains apart from wheat contain gluten?
They are all destroyed in the heat of the oven during baking, but their flavorful by-products remain. Be careful not to make the icing too runny. In yeasted products such as bread or vienoisserie, sugar also acts as a food for the yeast, kick-starting fermentation and helping the product to rise. Both ingredients draw out water from the yeast, slowing them down. 200g chopped hazelnuts or walnuts (optional), Gently melt together the butter and chocolate, In a separate bowl mix together the flour, baking powder and sugar, Beat in the eggs followed by the melted butter and chocolate mixture, Pour into a 150 x 200mm oiled and lined baking tray and bake at 180C/350F/Gas 4 for 30 mins. Besides flavor, salt helps to strengthen the gluten network in a bread dough, allowing it to trap more carbon dioxide and give volume to the loaf.
