Alfalfa is a kind of spice that is grown in every household only here in Ankang, Shaanxi Province. Every 9-10 days, we plant two parts in the field and they will be mature. When they are mature, we will harvest them at this time. The streets are full of fresh alfalfa. If it's not sold out, dry it, then put it in a plastic bag and put it in a cool place to keep it fresh. Don't get wet. If it gets wet, it will easily become moldy and insect prone. When making soup, add some alfalfa to make it especially fragrant. The way we usually eat it is to steam steamed buns and cook potato soup with some alfalfa to make it extra delicious. You can add alfalfa to any soup or stew. A pound of alfalfa can last for a long time. The stalks are hollow. The alfalfa seeds can also be ground into powder, which is very good for cooking spices.
