Practice. Ingredients: Oil dough: 140 grams of medium flour, 55 grams of powdered sugar, 15 grams of butter, 65 grams of pastry: 110 grams of low-gluten flour, 55 grams of Anjia butter. Filling: 240 grams of red bean paste, 12 self-grilled salted duck egg yolks.

Steps: 1. Sieve the flour and oil skin ingredients, mix and knead well, put it aside in a plastic bag and let it rest for 30 minutes. 2. Making puff pastry: sift low flour and mix with softened butter and place in a plastic bag to rest for 30 minutes. 3. Soak the egg yolks in cooking oil for 2 hours in advance, spray high-strength white wine and bake in a preheated oven at 180 degrees for about 5 minutes. Just watch to avoid oil coming out of the oven. 4. While the dough is relaxing, divide the bean paste filling into 12 portions, press them into a nest shape, and put an egg yolk on them. Do not cover them all and leave a little space.

5. Divide the relaxed dough evenly into 12 portions. 6. Wrap the pastry with oil dough, with the seam facing down, flatten it with your hands, use a rolling pin to roll it up and down from the middle, and roll it up 3 times from top to bottom. Then start from the first one and roll it out twice. Use the same method to roll it out and let it rest for about 15 minutes.

7. Pick up a rolled dough and press it in the middle to make the two ends tilt upward. Use your hands to gather the irregular edges toward the center and flatten them into a round shape. 8. Place a piece of bean paste and egg yolk stuffing, use the tiger's mouth to close it upwards and pinch it tightly, arrange it slightly and place it in a greased baking pan with the seam facing down.

9. Brush the surface with egg yolk liquid, and use the head of a rolling pin to stick black sesame seeds on the top of each egg yolk shortbread embryo. 10. Preheat the oven to 200 degrees, with the upper heat at 200 degrees and the lower heat at 180 degrees. If the upper and lower heat cannot be adjusted independently, set it to 190 degrees. Bake the middle layer for 25 minutes. If you press the edge lightly with your hand, if there is a layered texture, it means it is baked.
