Most of you will probably never have to cook rice for 100-120 or so, but I did it last night. Thanks to Ken Brown for this recipe.
1.5 gallons water + 1.5 cups
1 gallon rice
cup of butter or margerine
Stir together in deep hotel tray. Seal tightly with foil. Place in convection oven at 400 degrees for 50 minutes. Carefully peel back the foil and fluff.
