Yellow paste: mix egg yolk, powdered sugar, sesame oil, salad oil and water, stir until there are no oil drops, leave it for emulsification for a while, and sieve in the mixed low flour and corn starch.
Protein paste: add a few drops of white vinegar to white sugar in three times and beat until it becomes hard and frothy.
Mixed cake paste: Add the egg yolk paste into the egg white paste three times, and stir left and right without drawing circles.
Add onion and sesame seeds and stir well.
Put it in the preheated oven, 140 degrees for 25 minutes, 160 degrees 15 minutes. It basically rises to the highest point in 20 minutes, and the fragrance will fly out at 160 degrees! I'm loyal minister 30s oven.
