1. Mix all the ingredients and knead until the surface of the dough is smooth. Put the water slowly depending on the situation, and wrap it with plastic wrap for 1 hour.
2. Mix the ingredients into a dough, knead until the surface of the dough is smooth, wrap it in plastic wrap for 30 minutes
3. Salad oil, sugar and half of the warm water, stir until the sugar melts, then add the coconut
4. Slowly add the cake powder, add the other half of the water according to the dry and wet conditions, stir while adding, and then add the winter melon purée and knead until it is evenly formed into a dough.
5. At this time we have got three groups, each divided into 12 equal parts
6. Look at the organizational relationship. From top to bottom: water skin ball, oil skin ball, stuffing heart ball. Wrap it from top to bottom, it will form a pie
7. Roll the water skin ball into a round piece, wrap it around the oil skin ball, and gather it up with a tiger’s mouth
8. After wrapping, press it flat and roll it into an oval shape. Experts call it a bull tongue shape. Roll up the bull tongue from one end.
9. Flatten the rolled beef tongue, and then fold the left and right ends of the beef tongue in the middle, which is the so-called "folding quilt"
10. Flatten the quilt
11. Roll out the flat quilt to wrap a filling heart. Squeeze the tiger's mouth together and get a spherical cake
12. After wrapping, the seal is facing down, the sphere is pressed into a cake shape, and the cake is rolled into a suitable thickness with a rolling pin.
13. Brush the egg yolk liquid on the cake base, sprinkle with white sesame seeds, and use a knife to make a few cuts on the cake base to prevent the filling from bursting during baking
14. Preheat the oven to 170℃, middle level (I put the middle and upper level in the first pot, but the color was too fast, so I changed the middle level to the second pot)
15. If the color of the liquid egg yolk is deep enough, cover it with tin foil to prevent the color from being too dark or even zooming. Bake it for about 20 minutes
