From the can.I get all that regular item, not LTS type. I end up drowning in it from couponing usually.
Muffin mix gets used fast. Pancake mix....not so much. Honestly I need to just start not buying pancake mix unless it's free & even then probably donate it. We just don't care for pancakes / waffles much because they always make both kiddo and myself feel like crud afterwards.
I bought the potato slices back in 2018 on a lark - think they had a coupon on Auguson & potato slices was the cheapest thing I thought we'd have use for. I was more of a "very well stocked" person until covid hit & pushed me over the edge to "prepper adjacent".
*Best when stored in a cool dry place at temperatures between 55 Degree and 70 Degree F (ideal humidity 15%). *
* Potato slices (freshness preserved with sodium bisulfite). *
Ingredients are simple looks like. No oil added so they can advertise 25y shelf life.
Yes, I would open a can and give them a spin.
Do you have a crawl space under the house where it would be cooler for storage? Any place to put a root cellar?
