Can a sock help you in the kitchen? Absolutely. One use that is just coming to mainstream attention is using them to ripen avocados. If you put a not-quite-ripe avocado in a sock and leave it overnight, the next day it’ll be ready for use in your favorite guacamole. One lady, Diane Sherwood, a former caterer (she owned a catering company in Sun Valley, Idaho, swears by this trick so much that she released a product, the Avocado Sock, that you are just supposed to use to ripen avocados. It comes in four colors and costs $15.
