Hazelnut mantecados

Ingredients

• 200g all-purpose flour
• 200g hazelnuts (please use unroasted and unshelled hazelnuts where possible. Shelling and roasting them is not such a great effort and the flavor is much better. If you don't like hazelnuts, you can use almonds.)
• 150g powdered sugar
• 100g good quality pork lard
• 2 tsp baking powder
• A dash of olive oil
