Fo3 posted:Yeah, but they probably had a fire going for some other reason and didn't have to pay modern electricity rates I've always assumed the cost of cooking beans would be negligible, but Fo3 made me doubt myself, so I did some research. tl;dr: Beans are really cheap, no matter how you cook them. The difference between beans and other foods in terms of protein per dollar is enormous and, as long as you have either time or a pressure cooker, cooking large batches of beans will save you money. Also, I eat a lot of beans. Things I learned:
Average cost of cooking beans for 3 hours: (1.2 kW) * (3 hours) * ($0.11 per kWh) = $0.40 Maximum cost: (1.5 kW) * (3 hours) * ($0.20 per kWh) = $0.90 Here's a handy calculator: http://energyusecalculator.com/electricity_stovetop.htm Information is not abundant for pressure cookers, but I'd guesstimate that most electric ones would use 0.5-1.0 kWh per batch of beans, which would save you roughly 30-70 cents. I go through roughly 200 lb of dried beans in a typical year (yes, really), and I cook maybe 3 pounds at a time (I think?), so let's say 65 batches a year. The places I've lived have had cheap to average electricity, so using a pressure cooker has saved me at most $20/year, and it'll take my pressure cooker a few more years to pay for itself. In a place with expensive electricity, a pressure cooker would save more like $50/year. This is more of a difference than I expected (and there have been times in my life where it wouldn't have been negligible), but I think it's low enough that beans are still a cheap as hell source of nutrition even if you don't have a pressure cooker. Nothing else even come close in terms of protein per dollar. Unless you have IBS or something, beans are a great money saving recommendation. this post got really long, oops.

MohawkSatan posted:For soups you generally rinse it, for everything else that poo poo comes straight outta the jar. Unless you want a particularly acidic soup I guess?
