Ghee is clarified butter that you can get ready-made in Asian grocery stores. It can also be easily prepared at home. Here's how: In a saucepan, melt 454 g (1 lb) of unsalted butter and simmer for 20 minutes, skimming regularly. Pour the butter through a strainer: Voilà, it’s ghee. It keeps in the refrigerator for months. Why is it so popular in Indian cuisine? For its good taste of butter, of course, but also because unlike traditional butter, it doesn’t burn!
