STEP 1/3
Sieve the flour and almond powder and mix well with the black tea powder. Place at room temperature, add sugar powder and salt to softened butter, mix well, and add egg yolks two or three times.
STEP 2/3
Put the powder in the sieve and mix it well with a spatula. If the dough doesn't clump well, clump it together with your hands. Don't touch it too much. Make a cylindrical shape, roll it in a wrap, and rest in the freezer for 30 minutes.
STEP 3/3
Take out the dough and roll it in sugar. Cut into appropriate thicknesses and bake in an oven preheated to 170-180 degrees for 15-20 minutes. Depending on the oven, the baking time is different depending on the size and thickness of the cookie, so you have to adjust it.
