Heating up a mixture containing baking powder speeds up the chemical reaction, making the carbon dioxide gas form more quickly. It is best to add baking powder to ingredients last, as it starts to react as soon as it comes into contact with water. AQA video: Investigating how raising agents work. OCR topic exploration pack: teacher instructions: Raising agents. So what is the correct amount of leavener?
Some baked goods with a lot of heavy ingredients, like a carrot cake, may need a little more leavening, but not much. In most recipes, baking powder is preferred because of its reliability it contains exactly the right amount of acids to completely neutralize all the soda, leaving no aftertaste and because of its double action one acid dissolves when water is added, producing bubbles, and another acid does not dissolve and produce leavening until a higher temperature is reached in the oven.
This product may use encapsulation, like time-release cold pills, to produce leavening at different times. Baking soda is normally used in recipes that contain acidic ingredients such as sour cream, buttermilk, brown sugar, or chocolate.
Muscle-man soda is often the culprit. Frequently, overleavening is caused by an excessive amount of soda. A test kitchen asked me about a cake recipe that called for adding boiling water to the soda, letting it stand, and then combining it with other ingredients.
Sometimes the cake worked, and sometimes it fell. What we figured out was that the recipe had too much soda, but if the cook allowed the soda to stand long enough with the boiling water, enough of the gases came off to prevent the cake from falling. Recipes like this are tricky, to say the least. These ratios are good to remember so you can evaluate recipes before you try them and so you can successfully tinker with or create your own recipes.
Note: Baked goods with a lot of heavy ingredients, like carrot cake, may need a tiny bit more leavening. Already a subscriber? Log in. When eggs and sugar are whisked together they trap air, this is a colloidal structure as two ingredients are mixed together.
Self-raising flour contains baking powder. It can be added to plain flour or other mixtures to produce carbon dioxide when liquid is added. Act as a raising agent when converted to steam. Different raising agents are used in different food products. The technical term colloidal structure means what is formed when at least two ingredients are mixed together.
