1) Found unopened, vacuum sealed canister of McCann's steel cut oats in back of cupboard. The expiration date is 12-12-2009. Can I still use them? If so, should I refrigerate leftovers? How long will they keep once opened?
2) Can I use steel cut oats for oatmeal choc chip raisin cookies?
3) Recipe makes 4 servings, should I cut down to 1/4 (just me in house) or will leftovers refrigerate?
