1, make dough, 300g whole wheat flour 1 bag of milk (you can also use 1 60g yogurt)1egg 5g yeast (yeast must use warm water! When it melts, boiling water will kill yeast, and the water temperature is too low to ferment. ) Knead the dough to ensure the humidity. If it is too wet, you can add some whole wheat flour. 3. Cover with plastic wrap for fermentation 1 hour.

2. The volume of the fermented dough is twice that of the original dough, as long as the dough does not shrink.

3. Vent the dough and divide it into several small balls. I made a 50-gram ball to meet my own needs. Cover the dough with plastic wrap and let it rise for 25 minutes.

4. Start preparing the stuffing, steam the purple potato and press it into mud.

5, prepare other fillings, red beans, meat floss, cheese.

6. Roll the dough into pancakes, spread the stuffing and knead it into buns.

7. Put the wrapped bread in a baking tray, ferment for 60 minutes, and bake for 20 minutes at 180 degrees, and cover it with tin foil for 10 minutes to avoid over-coloring.

8. The baked bread is cut, and black rice is added inside, which is also delicious.
