Both beets and chard are different varieties within the same plant family—beta vulgaris—and their edible leaves share a resemblance in both taste and texture. Beet greens are part of all good beets, but they behave like another vegetable entirely. Earthiest of cooking leaves, beet greens have an intense, mineral flavor that compliments the sweetness of the root and are thus taste delicious when the two are cooked together.
Attached to the beet's green leaves is a round or oblong root, the part conjured up in most people's minds by the word "beet." The sweet taste of beets reflects their high sugar content making them an important raw material for the production of refined sugar; they have the highest sugar content of all vegetables, yet are very low in calories It is difficult to believe how the hardy, crunchy often rough looking exterior of raw beets can be transformed into something wonderfully soft and buttery once they are cooked.
How to Store
If possible (or desirable) use the beet greens as soon as you can. We sautéed some the other night and were surprised how mild their flavor can be. If you haven’t tried beet greens yet—don’t just discard them without giving them a chance.
Store beets unwashed in the refrigerator crisper where they will keep for two to four weeks. Cut the majority of the greens and their stems from the roots, so they do not pull away moisture away from the root. Leave about two inches of the stem attached to prevent the roots from "bleeding." Store the unwashed greens in a separate plastic bag where they will keep fresh for about four days. Raw beets do not freeze well since they tend to become soft upon thawing. Freezing cooked beets is fine; they'll retain their flavor and texture.
Tips for Preparing Beets
Despite their appearance, beetroots aren't as hardy as they look; the smallest bruise or puncture will cause their red-purple pigments, which contain beneficial flavonoids called anthycyanins, to bleed, especially during cooking. Cook beets lightly. Studies show beets' anti-cancer activity is diminished by heat. Don't peel beets until after cooking. When bruised or pierced, beets bleed, losing some of their vibrant color and turning a duller brownish red. To minimize bleeding, wash beets gently under cool running water, taking care not to tear the skin--this tough outer layer helps keep most of beets' pigments inside the vegetable. To prevent bleeding when boiling beets, leave them whole with their root ends and one inch of stem attached.
Beets' color can be modified during cooking. Adding an acidic ingredient such as lemon juice or vinegar will brighten the color while an alkaline substance such as baking soda will often cause them to turn a deeper purple. Salt will blunt beets' color, so add only at the end of cooking if needed.
Since beet juice can stain your skin, wearing kitchen gloves is a good idea when handling beets. If your hands become stained during the cleaning and cooking process, simply rubbing some lemon juice on them will remove the stain.
A Few Quick Serving Ideas
-
Grate peeled, raw beets for a delicious and colorful addition to salads, salsa or decorative garnish for soups.
-
For composed salads, cook beets only until they lose their rawness (not their crunch). Chill in cold water, peel, then cube before combining with smoked meat or fish, grains, fruit or nuts.
-
Bake beets for maximum flavor, sweetness and ease of peeling.
-
Add chunks of beet when roasting vegetables in the oven.
