Thanks to everyone for your replies.

There are at least a billion ways to cook rice but the way I've adapted for trail use is:

1/3 c rice and 1 c water (1:3 ratio). Soak rice at least 10 minutes. Bring to boil and boil for 4-8 minutes (1 oz of alcohol will do this for me). Insert into cozy. After 10 minutes drain any excess and let stand 5 more minutes. If there is any water it should be just a dribble. You may need to adjust the water based on the quality and freshness of your long grain rice.
