Lemon Hearts

 
250 g all-purpose flour
130 g margarine or butter
150 g caster sugar
3 egg yolks
grated zest of 1 lemon
½ tsp baking powder 
50 g icing sugar
1 tbsp lemon juice
1 tbsp water 
 
1.  Preheat oven to 220oC (425oF). Mix flour, margarine, sugar, egg yolks, lemon zest and baking powder together. Beat well to form a dough. Leave to stand in a cold place for a short time.

2.  Roll out the dough fairly thickly. Use a heart-shaped cookie cutter, cut out cookies and arrange on a baking tray. Bake for about 12 minutes, or until golden brown.

3.  Mix the icing sugar, lemon juice and water to ice the hearts.
