I’ve seen runs on pasta, rice, and bacon.
~~~
First thing I bought several weeks ago was rice. Cheap, lasts long, and goes a fairly long way. With as cheap as it is, I figured it wasn’t a wasted investment if the whole thing blew over without problems.
I thought about flour but to bake bread you typically want to use milk (although not necessary) and a lot of other baking has eggs in the recipe. So I passed on flour for the most part.
Food, particularly cheap grains and such, are not going to disappear unless society collapses completely, and if society collapses completely, you’ll have much bigger problems than lack of food. Self defense comes to mind first and foremost. All bets are off at that point. You may have to be on the move, allying with larger groups, and adapting to fast changing conditions. You wont likely be carrying all your bacon around.
When I had a bunch of chickens, I could count on almost one egg a day from each.
But; if you have DUCKS; they also are as prolific, but the eggs are TWICE the size (and they taste just the same) as the chicken ones. (and are tinted green!)
