Mess o’ Greens
My mom used to cook greens in such big batches that she would wash them on the rinse cycle in the washing machine. For her, a “mess” was a discrete unit of measurement equal to approximately one large grocery bag full. I think most Southerners operate under this assumption, at least as far as greens are concerned. It may seem like you’re starting out with far more greens than you’ll ever need, but keep in mind that they’ll cook down quite a bit. If they don’t all fit in the pan at first, start with as many as will fit and add to the pot as the greens cook down.
