1. Prepare all materials and tools in advance
2. Separate egg white from egg yolk, take only the egg white
3. 15 grams soft white sugar
4. Formula milk 50g
5. The egg whites are fish-eye-like
6. Add soft sugar
7. The egg whites must be beaten until they are hard (this step is very important and is the key to successful production)
8. Quickly add milk powder
9. Quickly cut and mix evenly to no particles (this step also needs to be very fast and light in action)
10. Pack it into a piping bag to extrude the pattern
11. Preheat the oven in advance, and fire up and down at 130 degrees for 50 to 60 minutes (the original recipe is 100 degrees but my oven has 130 degrees)
12. Once out of the oven, it can be easily taken off and it is ripe. If it is still sticky, you need to bake it for a while.
13. It melts in one bite and is very delicious
