Cake yeast, also known as fresh yeast or compressed yeast, is a type of yeast that is used in baking. It is called cake yeast because it comes in the form of a solid block, similar to a piece of modeling clay. This type of yeast is best suited for baked goods that require a longer rise time, such as brioche or other sweet doughs.
One of the main advantages of using cake yeast is that it provides a more intense and complex flavor compared to other types of yeast. This can be especially beneficial when making rich and flavorful breads, as the yeast helps to enhance the overall taste of the final product. I have personally used cake yeast in my baking and found that it adds a wonderful depth of flavor to my breads.
To use cake yeast, it must first be dissolved in a liquid before incorporating it into the dough. This is because the yeast is not in an active state and needs to be activated. Dissolving the yeast in a liquid, such as warm water or milk, helps to wake up the yeast and get it ready for fermentation. I have found that using warm liquid, around 100°F (38°C), works best for dissolving the yeast.
Once the yeast is dissolved, it can be added to the rest of the ingredients and mixed together to form the dough. The dough should then be allowed to rise for a longer period of time compared to using other types of yeast. This is because the yeast in cake yeast takes longer to activate and ferment the dough. I have found that allowing the dough to rise at room temperature for at least an hour, or even overnight in the refrigerator, helps to develop a better texture and flavor in the final baked goods.
It is important to note that cake yeast has a shorter shelf life compared to other types of yeast, such as active dry yeast or instant yeast. This is because cake yeast contains a higher moisture content, which makes it more perishable. I have learned from personal experience that it is best to use cake yeast within a week of purchasing it, or it can lose its effectiveness.
The use of cake yeast in baking can result in delicious and flavorful breads and pastries. Its unique flavor profile and longer rise time make it ideal for recipes that require a richer taste and a more tender texture. However, it is important to keep in mind the shorter shelf life of cake yeast and use it within a week of purchase for best results.
