Practice of sweet potato syrup

Peel the potatoes, cut them into cubes about 3 cm, put them in a container that can be put into a microwave oven, pour some water that the potatoes haven't finished eating, and microwave for 5 minutes. If the potatoes are steamed or boiled, add three or five spoonfuls of water when making mud after cooking to adjust the humidity of the dough. Taro contains more water, so add half less water.

Mature potatoes are pressed into mud. If there is no special mud press, you can use a wooden shovel with holes or a colander with holes to press it.

Mix sugar and cassava flour into mashed potatoes and stir well until there is no powder in the pot and the dough is no longer sticky. If the dough is cracked, it means it is too dry. You can adjust it by adding a tablespoon of water. Three kinds of potatoes can be made into other three colors, purple potato can be turned red with a spoonful of lemon juice, sweet potato can be added with matcha powder, and taro can be slightly mixed with purple potato and kneaded into various mashed potatoes and sweet potato syrup. Third step
