Shoutout to my grandma in El Paso who called my beans "soup" and fixed my grocery bill
When I moved into my first place back in 2009, I was spending about $60 a week on canned beans and boxed sides because I didn't know how to cook dry ones. My grandma visited from El Paso, took one look at my pot, and said "mijo, that's soup, not beans" and showed me to rinse and soak the pintos overnight with a little salt. Now a $2 bag of dry beans lasts us two weeks of meals instead of a few days of cans. What's the one cheap staple your family swore by that you had to learn the hard way?
