Note: 1. Almond sponge cake is one of the most commonly used basic cake germs in French desserts, which has many uses. The method is similar to the egg sponge, but also contains Qi Feng's protein dispersing method; its taste mainly depends on protein regulation, with less protein, the taste is more solid, and with more protein, the taste is softer. I added a little more protein. 3. As for sandwich filling, you can use the same amount of egg yolk instead of protein to make coffee yolk cream filling. The method is the same. Use egg yolk to taste better. 2. The production process seems to be complicated, mainly because I shoot too detailed and talk too much. In fact, it's just a cake body, a sandwich filling and a noodle. Let's use our imagination and combine freely! 3. The precautions in the production process are explained in each step and will not be repeated.
