How to cook
Knead a dough after pouring the lemonade and melted lard to the beaten egg.
Add the sugar, baking powder, stir well and add flour, as much as it absorbs, and knead. Leave for 10-15 min. and then roll it out.
Fold the treats in half, put them in an oven dish and press their edges with a floured fork (so it doesn't stick to the dough).
Bake in a strong oven. They bake quickly.
While still warm, sprinkle the ready treats with powdered sugar mixed with the vanillas.
