Egg yolk biscuits

Overview

How to cook Egg yolk biscuits at home

Beat four egg yolks with two whole eggs and powdered sugar
Whisk until the whisk head is lifted, the egg liquid will not fall down quickly, and the traces of the falling egg liquid will not disappear soon
Sift in the flour and baking powder in 3 batches and mix
Stir until there is no dry powder
Put it into the prepared piping bag and use a large round nozzle
Squeeze onto a baking sheet lined with greaseproof paper, be sure to pay attention to the gaps, otherwise they will all stick together when baked. I squeezed in too tight. Bake in the middle rack of the oven at 170 degrees for 18 minutes
After cooling, separate it from the oil paper and store it in a sealed bottle to ensure crispiness
