Hi -- I am Snack Mama at preschool tomorrow and I want to cook oatmeal (the 5 minute kind). I know that the basic ratio is 1 c of water to 1/2 c of oats -- but you lessen the water as you multiply. I'll need about 25 servings. My thought is to do 2 batches of 12 (since I don't want it sitting around for too long). Does anyone know how much I should reduce the water by? For 6 c of oats, how much water? And how much salt? Also, what are some fun mix-ins (not nuts) besides raisins, brown sugar & cinnamon? Thanks.
