Put white flour, yeast, warm water, butter and sugar into a basin to form dough, cover it and ferment for about two hours. Cut the dough and see that there are many small holes in the cross section to form the dough. Chop the minced pork and shallots for later use. Chop the beef and garlic together so that the garlic flavor can fully enter the minced beef. Although the slag-dropping sesame seed cake is made of pork, the "slag-dropping" can also be made of beef. Pull the dough into the same size, press it into a two-inch pancake, and make a small hole in it with a toothpick to avoid bulging when baking. Brush pepper, pepper, cumin and salt evenly on the cake. Finally, put the cake blank in the oven, adjust it to 190 degrees, bake it for 20 minutes, and the home version of "slag-dropped sesame cake" will be freshly baked.
