Preparations

• Drain the sauerkraut by placing it in a five sieve, which is placed in a bowl.
• Cut the shallot in small cubes.
• Soak the sultanas for 10 minutes in warm water.
• Preheat the oven on 185 degrees Celsius or 365 degrees Fahrenheit.

Cooking

• Melt the butter in a baking pan. Add the shallot and bake until caramelized. Then you can add the drained sauerkraut, cumin and raisins. Bake this for 5 minutes, and turn off the heat.
• Cut 8 squares of the puff pastry. Divide some spicy mustard in the middel of the squares.
• Break the egg in a small bowl, and mix the egg yolk and egg white.
• Use two forks to transfer some sauerkraut mix to a square. Place the sauerkraut in the middle. Divide some egg on the sides and close the puff pastry by folding the square into a triangle.

Baking

• Place all the pastries on a baking papier, which is placed on a baking sheet. Brush the pastries with some egg mix, and bake them until the pastries are puffed up and golden brown. This probably takes about 10 minutes.

Serve directly :)
