I bought a very large bag of rice, but it didn't come with directions on how to cook it. This is what works best for me:
1. Put cold water and rice at a 2:1 ratio in pot.
2. Add salt and butter to liking.
3. Bring to a soft boil until craters form (see picture). Then cover and simmer for about 20 minutes.
4. Fluff with fork.
