To store turnips, first separate the greens from the bulbs. Store the greens separately in a plastic bag in the refrigerator, and do not wash until just before use. Store the roots in a loose plastic bag in the refrigerator for up to a month or longer.
Substitute for potatoes in almost any potato recipe
To freeze turnips, first wash and slice to desired size. Blanch in boiling water for 2-4 minutes depending on size, then transfer to a bowl of ice water. Drain and place in a freezer-safe, airtight container for storage.
