So, if you're not going to prepare your potatoes right away, keep them out of the light. If you can, store them in a dry, dark place, that's the best.
At my house, I'm afraid that if they're not in my veggie basket I might forget about them and then they'd rot. So my big idea is to keep them in their same place only to cover them with a thick, dark dish towel.
Thanks so much to zabmo and morguefile.com for the perfect photo!
