I making this from scratch tonight, as an experiment to see whether the canned stuff is any better than homemade. Most directions I have found say to take a can of condensed milk and boil it in plenty of water anywhere form 1-4 hours, then let it cool and enjoy. My question is, if I boil it and let it cool, can I keep it in the can, unopened and unrefridgerated for a few days, or does the boiling take that option away? I want to do two cans and save one to use on Friday.
Thanks for your help!
