I’ve not had flour go rancid but to save from trashing put it into the compost. Supposedly, sprinkle it onto plants to keep the bugs away. Have you ever tried it on bugs?
No, have not tried it on bugs. I bought flour at the store, brought it home, and lo and behold there was bugs when I opened it. I put it in the compost. This happened 3 times in a row.
So I went to the LDS website and ordered 3 cases of flour. Each case has 6 #10 cans. I don’t use much flour or sugar either for that matter. I grind wheat and flax seed and use it about half and half when I do bake something.
The use by date is 20 or 30 years from now. No more bugs for me.
