Beets will stain your hands and countertops. Be prepared to wipe/wash things often. Don't wear your favorite Summer Whites while working with beets. You don't need to peel smallĀ beets - the skins add nutrition and fiber. However, if your beets are big and gnarly with thick skins, you'll probably want to peel them before roasting. Soaking the cashews plumps them up which makes them softer and easier to blast in the food processor which contributes to the smooth, creamy texture of the end product.
