1. Look at the feel

When buying yams, you can pick them up and compare them. High-quality yams generally have a heavier feel. In other words, for yams of the same size, be sure to choose heavier ones. At the same time, you can also feel the firmness of the yams, because high-quality yams are relatively firm inside.

The cross-sections of fresh and high-quality yams are snow-white and contain mucilage. If the mucus on the cut surface is watery, and the cut surface has turned yellow like rust, or even the cut surface has turned black, do not buy it. These are stale yams.

In order to retain most of the nutrients of yam, it is best to use the "steaming" method when eating it. If you "cook" it and eat it, it will not only dissolve some of the nutrients, but also destroy the flavor of the yam itself.

When the meat filling changes color, add the diced mushrooms and stir-fry until fragrant.
