You can buy whole ingredients in bulk and make your own foods.. Humans have allowed themselves to be controlled by conveniences. Stop it.

How much does a jar of organic raspberry jam cost? I don't know. I make it fresh for when I want it, using two ingredients - maple syrup and frozen berries I buy when they're on sale. Put in a pan, simmer until desired thickness....

Bread, biscuits, pancakes, crumpets, pasta, cakes, pie crust, etc..? Easy to make, especially if you buy already ground flour, unlike me. I have to be a penny pincher and buy whole grains that I grind myself.. A two pound loaf of sourdough bread doesn't require two pounds of flour. And even if you spend more on organic flour, it's cheaper per loaf than that shit in plastic bags - unless you're picking up the absolute cheapest on the shelf. In any case, it'll be 3-ingredients (flour, water, salt) vs the dozen+ on storebought and will have far more nutrient density.

Beans, super easy to make.. A $.99 can of beans is a rip off. Some dry beans are that much per pound.

I've been buying grains from azurestandard because they're the cheapest I've found at the moment. I have two other sources, that have difficulty stocking what we use most.
