One can never have too much sugar.LOL
I buy a bunch of sugar everytime it goes on sale. Libs like that guy in New York may decide to ban it or tax the devil out of it. So I say stock up it lasts almost forever.
I also plant sugar beets. I have the directions for processing sugar beets to make syrup or sugar granules, just in case I haven’t stored enough.LOL
It’s hard to stock up here. A couple weeks ago I tried to buy flour and they had 3 10lb bags. Two were ripped open and the third I had to crawl on my hands and knees and use a long spoon from the display to dig out from the back corner. Same with the sugar. I’m not talking just one brand of sugar but ALL the sugar shelves were empty. My one and only bleepin’ well known chain store (HEB) always has empty shelves. If the weekly ads have a sale, poof!, that shelf is empty.
Sugar beets and stevia are already on my wish list and I’ve printed out how to turn them into sugar.
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?
