Mini Hazelnut and Chocolate Tarts

My mom came to visit us in April and as it usually happens when we have visitors I have an opportunity to bake more and try new recipes.
This is a very easy recipe, though it looks lovely and it goes well during tea/coffee time. These small tarts with crunchy fragrant crust are not too sweet, strawberries bring refreshing touch to dark chocolate filling.
Recipe adapted from BBC goodfood.
1 cup AP flour
2,5-3 tb.s. blended hazelnuts
pinch of salt
100g vanilla powdered sugar
90g cold butter (chopped)
1 egg
80g dark chocolate
80-100 ml heavy cream
1 tb.s. liquer (hazelnut)
some strawberry preserves
12 t.s. blended hazelnuts
6 halved strawberries
chocolate sprinkles

Judas Trees are blooming in April and May and this is the most beautiful time of the year here in Istanbul. Though the weather is not the best this year.

Place into blender all dry ingredients for the crust and add butter and whiz until they form crumbs. Add an egg and blend again. The dough should form a ball now. If too soft add some more flour.
Roll the dough into a 5mm disk and cut out rounds (app.6-7cm diameter). Sprinkle 12 muffin tins with flour and place rounds of dough into each muffin cup, press them with your fingers.
Chill in the freezer for 15-17 minutes.
Preheat oven to 160C. Bake in the middle for 15 minutes. Let them cool a little.
Microwave chopped chocolate and cream. Mix well and pour liqueur into it. Add 1 t.s. of strawberry preserves and 1 t.s. of hazelnut crumbs into each tart. Pour some ganache over hazelnuts. Place strawberry halves into each tart. Refrigerate until serving.
