1In a large bowl, mix the flour and almond flour together.
2Finely chop 3 tablespoons of the butter, and cut the remaining 5 tablespoons into cubes. Keep them in the refrigerator without mixing them together.
3Mix the yogurt with 1 tablespoon of water and place it in the refrigerator.
4Add 1 tablespoon of granulated sugar and the salt to the flour mixture. Add the cubed butter to the flour and work it in until the pieces become small. Then add the remaining butter and bring the dough together.
