Peel the sweet potatoes, wash them well, boil them in water and add rock sugar. It seems very simple. But many people cook sweet potato water, sweet potato color brown, potato has been cooked, sugar water in the precipitation of sweet potato powder.

The color of the sugar water cooked in this way is also not clear enough.

Potato is good. It contains tannins and oxidizing enzymes. But these turn brown when they meet iron. Sweet potatoes contain pectin, which we call sweet potato milk, and pectin also accelerates the decomposition of starch during the heating process. So it takes know-how to cook a bowl of sweet and flavorful sweet potato sugar water.

Tip 1: Avoid exposing sweet potatoes to iron. It's best to scrape the skin with a bamboo knife. Then pry it into chunks. (For good looks, I cut the sweet potatoes into four-square cubes with an outline knife).

Tip 2: After cutting the sweet potatoes into cubes, soak them in water for about five hours. Change the water frequently during the soaking period. This is to allow the pectin in the sweet potato cubes to dissolve out.

Tip 3: After soaking, take out the cubes of sweet potato to dry.

Tip 4: It is best to use a wok, first bake the bottom of the wok, then use a little lard, burst a piece of flattened ginger through, fry the potato pieces, add water to cook.

This sweet potato syrup looks complicated. I omitted the last process. But add one more ingredient: lily of the valley.

The lilies are added after the sweet potatoes are cooked and the rock sugar is added. This way the lilies are also fresh and tasty. However, if you use sweet potato cubes soaked in water to cook sweet potato water, the potato cubes are powdery and tough, the soup is clear and sweet, and the taste is smooth, so you can eat it hot or cold, and it is attractive.

With two different varieties of sweet potatoes, coupled with a hundred contracts, yellow, purple, red and white colors, is quite pleasing to the eye.
