I've finally gotten my steel-cut oats recipe nearly perfect and I'm trying to figure out how long I can store them (so I know how much I can make at once). Basically I'm doing a double-boiler setup in a ball jar cooking the oats for 45 minutes to an hour and then putting on the lid and then refrigerating for later use.
Normally milk will go bad after a couple weeks in the fridge but I assume boiling and vacuum sealing will extend this time. I'm not really familiar with canning though so my assumption might be wrong.
How long should I expect milk to last in the fridge when boiled and sealed in a Ball jar?
