Starch-free Version-icing Yam Beans
1.
Rinse the yam beans with water, add an appropriate amount of flour and rub repeatedly to wash the magazines on it.
2.
It is best to rub it with flour twice.
3.
Steam the washed yam beans in a pot for 10 minutes.
4.
The steamed yam beans are dried in moisture.
5.
Pour a little water and white sugar into the pot and boil the syrup over low heat.
6.
Wait for the syrup to become silky.
7.
Add a little white vinegar to the syrup.
8.
Pour in the cooked yam beans and stir quickly. Pour in as many yam beans as possible. The mixing speed must be fast, so that each yam bean is coated with syrup (if you like thicker frosting, pour less yam beans) .
9.
The finished product (because I don't like sugar very much, only a thin layer of frost is hung on the yam beans).
