I'm building a pantry - not the physical holder of foods, but the actual food in it.
Just before the pandemic started I was baking our own bread. But after March, >poof< I could no longer get flour; I was buying it on an as needed basis. Luckily we could still get bread from the store. But, man, two years ago things were weird!
But since then, I've given a lot of thought to building a store of food to last six months or so. I had some discussions with my mom, because I remember her canning a lot. And I remember her canning a lot because we kids were drafted into the prep. I remember peeling carrots, chopping green beans into 1-1/2" pieces, etc. So, I asked her - why did you do that? I thought for sure I was going to get a reason like "food security" or we were gathering in the harvest to last through the winter months. But what she said instead shocked me. (remember this was two years ago) She said that inflation was so bad in the 70s that every time she went to the grocery store prices were higher and higher, so she turned to canning to alleviate that issue.
I didn't think anything about inflation until this year. And frankly, after my last grocery shopping trip I noticed a lot of things have almost doubled in price. At my local ALDI's I was getting butter for 2.99 - it's now 3.58; eggs were 1.27 doz, now 2.07, and all the produce is up. Some things didn't go up yet like sugar, flour, canned soups, coffee. So, I bought a flat of canned beans, a little extra coffee, and a few bags of rice (which was also up in price).
I'm not doing this out of fear, but out of prudence and being a wise steward. Since 2 years ago I've had some leeway in my grocery budget for building a pantry storehouse, and I've done quite a bit.
