160 grams flour
100 grams sugar
60 grams butter
2 tablespoons lemon juice
2 teaspoons grated lemon zest
1 egg
½ teaspoon baking powder
Sift the flour with the baking powder, add the grated lemon zest, stir well and set it aside. In another bowl, beat the butter and sugar until light and fluffy, then add the egg and the lemon juice and blend. To that, add the flour mixture and mix until it forms a very soft dough. Put the dough in the fridge for about half an hour, to chill; then divide it into 16 cookies, arrange them on a cookie sheet lined with baking paper, and bake in a preheated oven, at 180˚C, for 10-12 minutes.
