Lemon biscuits

An idea for an edible gift: pack the biscuits into a pretty bag and tie it with a ribbon.
Ingredients
- butter — 100 g
- sugar — 100 g
- eggs — 2
- vanilla sugar — 1 tsp
- zest of two lemons
- juice of one lemon
- salt — a pinch
- flour — 340 g
- baking powder — 1 tsp
- icing sugar — 50 g
Method
- Beat room-temperature butter with the sugar.
- Crack in two eggs and keep beating.
- Add the vanilla sugar and a pinch of salt. Add the lemon juice and zest.
- Add the flour with the baking powder and bring the dough together.
- Roll the dough into balls and coat them in icing sugar. Put them on a plate or board and freeze for 30 minutes — this is what gives the biscuits their cracks. After freezing they can be rolled in icing sugar once more.
- Bake in an oven preheated to 180°C for 15–20 minutes.
