First, beat the egg whites with a whisk, mix the trimoline, add sugar powder, and mix it so that there is no dry powder. I didn't have trimoline, so I used starch syrup. Put the almond powder and white rice powder on a sieve and mix them well so that you can't see the raw powder. You can mix white rice powder, almond powder, and sugar powder in a sieve.
