Gelatin is a versatile ingredient that is commonly used in baking and pastry making. It is a protein derived from animal collagen, and it is used to give structure and stability to a variety of baked goods. In this blog post, we will explore how bakers can work with gelatin and discuss the differences between powder and sheet gelatin.
One of the most common uses of gelatin in baking is as a gelling agent. It is used to create a firm but flexible structure in products like jelly candies, gummy bears, and fruit snacks. It is also used to stabilize mousses, creams, and other creamy desserts. In these applications, gelatin acts as a thickening agent and helps to hold the structure of the dessert together.
There are two main types of gelatin that bakers can use: powder and sheet. Powder gelatin is the most common form of gelatin and is sold in small packets or jars. It is made by grinding down collagen from animal hides or bones into a fine powder. To use powder gelatin, you will need to "bloom" it in cold water before adding it to your recipe. To bloom gelatin, sprinkle the desired amount of powder over a small amount of cold water and let it sit for a few minutes. This will allow the gelatin to absorb the water and become soft and pliable. Once the gelatin has bloomed, you can add it to your recipe by heating it gently until it is fully dissolved.
Sheet gelatin is a more concentrated form of gelatin that is sold in sheets or strips. It is made by purifying and drying the collagen from animal hides or bones. To use sheet gelatin, you will need to soften it in cold water before adding it to your recipe. Simply place the desired amount of sheets in a bowl of cold water and let them sit for a few minutes. Once the sheets have softened, you can remove them from the water and gently squeeze out any excess water before adding them to your recipe.
One of the main differences between powder and sheet gelatin is the way they are measured. Powder gelatin is measured by weight, whereas sheet gelatin is measured by the number of sheets. This can make it a little more challenging to convert recipes that use one form of gelatin to the other. However, as a general rule, you can use the following conversion: 1 teaspoon of powder gelatin is equivalent to approximately 4 sheets of sheet gelatin.
Another difference between the two types of gelatin is the way they set. Powder gelatin sets more quickly than sheet gelatin, which means that it is a good choice for recipes that require a quick setting time. Sheet gelatin, on the other hand, sets more slowly and produces a softer, more elastic gel. This makes it a good choice for recipes that require a softer, more delicate structure, such as mousses or fruit snacks.
When working with gelatin, it is important to keep in mind that it is a protein and it will break down when exposed to heat or acidic ingredients. This means that you should avoid boiling gelatin or adding it to recipes that contain a lot of acid, such as citrus fruits or vinegar. Instead, gently heat the gelatin until it is fully dissolved, and try to use it in recipes that are neutral or slightly alkaline in pH.
In conclusion, gelatin is a useful ingredient for bakers and pastry chefs to have in their arsenal. It can be used to add structure and stability to a variety of baked goods and desserts. There are two main types of gelatin to choose from: powder and sheet. Powder gelatin sets more quickly and is measured by weight, while sheet gelatin sets more slowly and is measured by the number of sheets. Both forms of gelatin have their own unique properties and can be used in different applications.
