Trying to decide how far in advanced I can make up my peanut butter sandwiches and other things and they stay good.. I typically vacuum seal them and freeze them. Can they sit for a few weeks before I grab and go?
You'll want to freeze and then seal. Trust me on this! I bag up dry stuff, label it, and store it in one of those plastic "ammo-cans" that have a gasketed seal. I've read that throwing a hand warmer or two in when you seal it up will absorb the oxygen and keep stuff fresher.
Take-a-Knee - What is the outcome if you seal then freeze? just curious, got me wondering of all the possibile weirdness that can happen to objects when frozen!
If you vac bag a soft piece of bread it flattens out into a thin layer. Your PBJ will end up being a 1/4 inch thick piece of mush.
