Orange Crinkle Cookies

Wash the orange thoroughly, scrub it with a brush, then blanch it three times with hot water to remove wax and chemicals. Grate the orange part of the orange peel on a fine grater.

Sift the flour with the cocoa powder, baking powder, and 70 g of powdered sugar. Add the beaten egg, softened butter, grated orange peel, and one teaspoon of orange juice. Knead into a sticky dough. Wrap it in cling film and let it rest in the refrigerator for at least 2 hours.

Divide the chilled dough into 25 equal parts, form them into balls, and immediately roll them thickly in sifted powdered sugar. Place the balls on a baking sheet lined with parchment paper, leaving plenty of space between them as they will expand during baking.
