Tools/Materials: yam bean, Cumin, Chili powder, black pepper, ginger, garlic, garlic sprout, oil and salt.

1. Wash yam bean first. At this time, if yam bean is stored improperly, it may deteriorate. So when cleaning, pinch it, and the broken yam bean will rot. It's best to pick out the stale and not full yam bean. Then put it in a pot and cook for about 10 minutes. After cooking, take it out and drain it.

2. Prepare all seasonings in advance. Cut ginger and garlic. Garlic seedlings are very fragrant. You can prepare a little more. Chili powder, cumin and black pepper are also put in the bowl. If you can't eat spicy food, you can leave the Chili powder.

3. Put the oil in the pan, add the ginger and garlic, stir-fry until fragrant, then add the cooked yam bean, add salt and stir-fry until fragrant, then add the cumin Chili powder and black pepper, stir-fry evenly, and finally pour the chopped garlic seedlings out of the pan.

Yam bean's selection method:

1, weighing: yam bean of the same size, weighing in your hand, the heavier the yam bean, the better. The heavier yam bean has more water content and a crisp taste, while the lighter yam bean is likely to be left for too long, losing moisture and nutrition and having a bad taste.

2. Look at the skin: yam bean with good quality, the skin is brown and smooth, without mildew and insect bites. The complete skin can better preserve the nutrients in yam, otherwise it will accelerate the loss of nutrients in yam, and it will not be soft and sticky and taste bad.

4. Look at the surface soil: When choosing yam bean, you can look at whether there is more soil in yam bean, because more soil will increase the weight of yam bean, which will lead to extra money when buying, so don't buy yam bean with more soil. But if there is no dirt at all, a clean yam bean is actually not good. If there is no dirt, it means that the yam has been placed for too long and the dirt has been scraped off.
