The first step of the old lady's cake is to make winter velvet stuffing. Select old wax gourd with ash, peel and remove seeds, steam it in a cage, take it out and beat it into velvet with a blender, then wrap it with gauze to squeeze out the water, put it in a hot pot with a little lard, add sugar and stir-fry it continuously, then tick out a certain amount of thicken according to the dryness to make it thicker, finally add cooked melon seeds and cooked sesame seeds, mix well, and take it out of the pot and cool it to get the stuffed winter velvet. Of course, you can also use wax gourd candy instead of wax gourd sauce as stuffing, which is easier to make: stir wax gourd candy into a paste, then rub it evenly with lard and Chaozhou powder (fried glutinous rice flour), and finally add cooked melon seeds and cooked sesame seeds and mix well.

Step two, do the skin. The crust of the old lady's cake in the Book of Rites belongs to pastry, which consists of oil core and water-oil crust. Its water-oil skin is made of 450g of low-gluten flour, 0/00g of high-gluten flour, 7g of baking powder, 0/0 of egg, 0/0g of lard and 0/0g of clear water. The oil core is made of 450g low-gluten flour, 350g cream and 550g lard.

The third step of the old lady cake is filling and baking. The crust is made by the method of small mouth and crisp. Take a small piece of water and oil skin, wrap a small piece of oil core, flatten it and roll it into the shape of ox tongue, then roll it into a cylinder from outside to inside, flatten it, fold it three times, and finally roll it into a circle, and the filling can be formed. The wrapped cake blank should also be pressed into an oblate shape, and two small holes should be cut on it with a knife (mainly to avoid the skin breaking caused by the expansion of the stuffing during baking), then the egg liquid should be brushed, sesame seeds should be sprinkled, and baked in the oven for about 10 minutes, thus making this delicious old lady cake.
