Cooking with Stored Root Crops

How do I tell if a stored root crop is still good?

Use your hands first. A good root feels firm and heavy for its size. Slight softness or wrinkling at the tip is common late in storage and often means the root has lost water, not that it has spoiled. Wet, slimy, collapsed or moldy spots are different, and those pieces should be cut away or the whole root discarded depending on how far the damage goes.

Smell matters too. A clean earthy smell is normal. A sour, rotten or fermented odor means break down is underway. Check the whole bin regularly, since one rotting root can spread trouble to its neighbors.

• Firm and heavy is good
• Wrinkled but firm is usable
• Slimy, wet or foul-smelling means discard
• Remove bad roots from the bin right away

What about potatoes that have sprouted or turned green?

Sprouts are the potato preparing to grow. Small sprouts can be snapped off, and a firm potato is still usable. A potato that is badly shriveled and covered in long sprouts has lost quality and may not be worth the effort.

Green skin is a more serious sign. Light exposure makes potatoes turn green, and the green areas are associated with compounds that can cause stomach trouble. Food safety sources advise cutting away green areas generously and discarding potatoes that are very green or taste bitter. For specific guidance, ask your extension office.

If you are unsure whether a potato is safe, the usual advice from food safety sources is to discard it. Potatoes are inexpensive compared with the cost of being ill, and your extension office can offer guidance.

How should I prepare roots that were stored for months?

Scrub rather than soak, and trim the tops, tips and any blemishes. Peeling is optional for most roots if the skin is sound, and unpeeled roots keep more texture in cooking. Older roots with tough skins are easier to handle if peeled.

Cut pieces to a similar size so they cook evenly. Roots that have softened a little respond well to long, moist cooking such as soups, stews and braises, where firmness matters less.

Beets and carrots that have gone limp can often be crisped in cold water before use, though that will not rescue roots that are truly soft or rotting.

What cooking methods suit each type of root?

Potatoes and parsnips roast, mash and simmer well. Carrots turn sweeter when roasted or cooked slowly in a little fat. Beets keep their color best when cooked with the skins on and peeled afterward. Turnips and rutabagas have a sharper flavor that mellows with longer cooking and pairs well with butter, apples or strong herbs.

Celeriac and winter radishes work grated raw into salads when they are still crisp, and cooked in soups when they soften. Try one method per root until you know what your household likes.

Roots roasted at home with oil can be stored in the refrigerator for a few days and reheated. Keep them in a shallow covered container and use them promptly.

How do I use up roots before they go soft?

Sort by condition every couple of weeks. Cook the softest first, and shift firm ones to the back. A big pot of roasted or mashed roots can be portioned and frozen for later, and a batch of vegetable soup uses a lot of tired roots at once.

If you want to can or pickle some roots, only use a current tested recipe from the National Center for Home Food Preservation. Root vegetables are low-acid, so untested methods carry real risk.

How do I handle food safety in the kitchen?

Wash hands, boards and knives after handling dirt-covered roots, since soil carries organisms. Rinse roots under running water and scrub them before cutting, even if you will peel them, so that soil is not carried in by the knife.

Cook roots until tender, and refrigerate leftovers promptly. Cooked potatoes in particular should not sit at room temperature for long periods or be held in sealed foil, which is a known botulism concern.
