When making stir-fried yam, clean the yam, peel it, cut it into pieces, blanch it in boiling water for two minutes, take it out, soak it in cold water, and stir-fry it in hot oil. The blanching time of yam should not be too long, so as not to affect the crisp taste of yam. Yam can be stir-fried or fried with carrots, sliced meat, fungus and other vegetables, and the taste will be richer.
Skills of purchasing yam
It should be noted that you should never buy yam with abnormal spots on the surface, because it may have been infected with diseases and there are likely to be a lot of pesticides left. This yam not only can not maintain health, but also will cause the body to be harmed by pesticides after eating, which is not worth the candle. In addition, it should be noted that the cross section of yam should contain mucus, and the skin is not damaged.
Yam is afraid of freezing and heat. When buying yam in winter, you can hold it by hand for about 10 minutes. If yam sweats, it is frozen. Looking at it, the cross-sectional mucus of frozen yam will turn into water, with hard heart and red flesh color, poor quality and extremely bad taste.
