When I clean and sort a cup of dry beans it takes a long time and I find myself discarding a good tablespoon of dirt, rocks and beans that don't look right. These are beans purchased in 1 pound packages for prices that seem like great bargains, when compared to canned beans, until I get into the cleaning and sorting again. I would rather cook from dry than eat canned, but I would also like to start with clean beans. Where can I find them? I am in Rochester Minnesota, US.
