Materials:
3 hand-grabbed cakes, 1 purple potato, 1 egg.
Exercise:
Peel, clean and slice the purple potato, and steam it in the pot.
Poke the purple potato gently with chopsticks or spoon, and it can pass easily, that is, when it is cooked, take it out and mash it with spoon. If the purple potato is dry, it can be diluted with some milk. )
You only need to use the yolk of the egg. protein can be used as other delicacies, and it won't be wasted! Stir the egg yolk.
Take out the cakes in advance, soften them at room temperature, tear off the diaphragm, stack three cakes, and roll them into thin rectangular skins with a rolling pin. If you can't roll out a rectangular skin, you can roll out the cake thinly and pull its four sides aside, so you can roll out a rectangular shape. )
Add purple sweet potato paste, roll it up, and knead it with your hands after rolling it up, so that the skin is tight.
Cut the rolled purple potato roll into small pieces with a knife.
Put the cut purple potato rolls into a baking tray covered with oil paper, brush a layer of egg yolk liquid on the surface, sprinkle a little black sesame seeds as an ornament, and put them in the oven for baking at 200 180 12 minutes. The baking time can be adjusted according to the firepower of your own oven. )
Bake until the skin of the purple potato roll is crisp and yellow, and then take it out. The pastry layer outside is very rich, so it's crispy outside and soft inside when you take a bite. Like a friend, try it quickly!
Tips:
To make this purple potato roll, it is best to choose the original hand-grabbed cake skin or flying cake skin. Now all the original hand-grabbed cakes in the supermarket are out of stock. I only bought onion-flavored hand-grabbed pastry crust and made this purple potato roll.
In addition to purple potato, the stuffing in the hand-grabbed cake can also be changed into sweet potato, bean paste stuffing, taro paste, mung bean stuffing and so on. All these are possible.
