Purple sweet potato is rich in selenium and anthocyanin in addition to the nutritional components of common sweet potato. Anthocyanin has the function of prevention and treatment for more than 100 kinds of diseases. It is known as the seventh essential nutrient after water, protein, fat, carbohydrate, vitamin and mineral. Can also lose weight. Can also beauty care oh. Let's move on, women.
Step1:Wash the purple potatoes. Put the skins into the pressure cooker and press them to be cooked. After the pressure cooker is exhausted, peel off. Take 150g and put it into the blender. Then add pure milk and sugar powder. Stir well. Mix the flour and glutinous rice flour evenly.
Step2:Put the mashed purple sweet potato puree (hot). Flour and glutinous rice flour into the mixing basin. Do not put all the flour and glutinous rice flour into the mixing basin. Leave some. Because the water absorption of each purple sweet potato is different. After mixing into a large wadding like dough, knead it into a non stick dough by hand, and feel the dough soft and tough.
Step3:Divide the dough into 11 parts. Each part is about 30g. If there are many members in the family, you can prepare 2 parts of raw materials. Cover with plastic wrap. Divide the red bean paste into 11 parts, about 15g each. Knead.
Step4:Make the purple potato dough into a small hat shape. Put the bean paste filling in. Close the mouth. Close the mouth downward. Reshape and make it round.
Step5:When pressing the purple potato, first stir fry 10 grams of glutinous rice flour with a small fire (the glutinous rice flour will change color. Don't stir and paste it. )。 After all the purple potato cakes are wrapped, each of them is pasted with a bit of fried glutinous rice flour (anti stick when pressing the mold. My family's is a 50g moon cake mold). Put some cooked powder on the moon cake mould to prevent sticking. Use the moon cake mould to press out the beautiful flower pattern. (there is no moon cake mold at home. It can be squashed directly. It can be turned into a small round cake.)
Step6:Boil the steamer. Put a layer of cooking oil on the steamer drawer. Then put the purple potato cake with bean paste on it. Cover it. Steam over high heat for 15 minutes.
Step7:After the purple potato cake is steamed, open the lid. Let it cool a little. Put it on a plate. You can eat it. The crystal sweet potato cake with bean paste filling is coming out.
Cooking tips:I use a pressure cooker to press the purple potatoes. It's slower to steam them in a steamer. Peel the sweet potato and cut it into thin slices or small pieces. Cover with plastic wrap when steaming. Prevent water vapor from entering. Also, do not peel when pressing in a pressure cooker. Peeling is easy to absorb water. We can try it. There are skills in making delicious dishes.
