Cooking Steps

1. 

   Step1:Cut the cooked egg yolk into pieces. I don't have a sieve, so I can chop it on the chopping board. Melt some butter. Put in some sugar. Stir it to make it white and swollen. Put in the egg yolk. Stir it a few times and put in the flour. Euryale powder. The ratio is one to one.

2. 

   Step2:Add the flour and knead it into a ball like a plasticine. Put it in the refrigerator for half an hour. Take it out. When the ball is pressed with your thumb, it will crack. Put it in the oven and bake. The edge will turn yellow.
