Rhubarb tart

The rhubarb in our vegetable garden is growing fast now: time to bake a delicious rhubarb tart! This is my favorite recipe.

Ingredients:
- 750 g rhubarb (cleaned and cut in small pieces)
- 15 g vanilla sugar
- 3 tablespoons custard powder
- 30 g sugar
- 100 g raisins

For the dough:
- 150 g sugar
- zest of 1 lemon
- 150 g soft butter
- 3 eggs
- 150 g self raising flour
- some salt

Mix the rhubarb, sugar, custard, raisins and vanilla sugar. Prepare the dough by mixing sugar, butter, zest and salt. Mix the eggs in, one at a time. Add the flour at the end and put the dough in a 24 cm spring form pan (greased and floured) and line bottom and sides. Fill the pan with the rhubarb mixture. Bake in the baking oven for almost one and a half hour.
