During the holiday season, sweet treats usually mean baked confections. But now is the perfect time to head to the farmers markets for vegetables sweetened by the cold weather.
Evangeline Sarat, co-founder of Sweet Land Farm in Ithaca, NY, says, “We get a nice fall frost before we harvest for winter and that makes things really sweet — kale, carrots, beets. We practically eat nothing but kale all winter!” The science behind this transformation is that the plants convert their starches into sugars, which lowers the freezing point — and subsequent cell breakdown — in those colder temperatures.
As mentioned in a previous VIV Says, kale is the trendy vegetable du jour, with good reason. This nutritional powerhouse is packed with vitamins A and C and more than 1,000 percent of your daily requirement of the antioxidant vitamin K, not to mention a good amount of calcium and fiber.
Sarat recommends a “massaged kale” salad that sounds as if it comes straight from the 50 Shades of Kale (Minerva Salus Publishing, 2012) cookbook! Simply rubbing the leaves for a few minutes breaks down that tough, fibrous texture, she explains. Or sauteé the kale in oil “with onions and garlic and add salt and pepper,” she says.
Sweet Land operates solely as a CSA, with a 14-week winter program that allows members to come to the farm and pick out exactly what they want. While carrots, onions and potatoes are usually the first to go, they grow several other “winter storage crops” (a.k.a. root vegetables) such as as turnips, rutabaga and parsnips. “People underestimate the awesomeness of parsnips,” says Sarat.
In Montana, at the Bozeman Winter Farmers’ Market, which is operated by Gallatin Valley Botanical, market manager Katie Meyer notes that the first frost tends to sweeten items like broccoli, kohlrabi, cabbage and Brussels sprouts. But it’s winter squashes and, of course, root vegetables that fill the market stands and the CSA baskets: beets, fingerling potatoes and Black Spanish radish, just to name a few.
Often rough and woody looking, root vegetables don’t often get the same respect as more colorful spring and summer produce. Root vegetables offer high nutritional value, plus they’re exceptionally easy to prepare — just peel, dice toss with olive oil and salt, and roast in the oven until tender and sweet.
Considered the ugliest root vegetable of them all is celeriac, or celery root. Underneath the familiar crown of celery stalks is a sprouting, knobby root. But the creamy white interior has a mild, celery-like flavor. Puréed, it makes a beautifully light alternative to mashed potatoes. Just dice the celeriac, cook it in a small amount of butter in a saucepan, and pour just enough milk to cover it (2 percent milk works, but whole milk provides a richer flavor). Let it come to a boil and then simmer with a pinch of salt until soft (about 20 minutes). Remove the celeriac from the pan with only a bit a hot milk mixture and place in a blender or bowl. Blend or mash with salt and pepper to taste. If it comes out too thick, just add more of the hot milk.
Below is a hearty roasted celery root purée with cipollini onion and bacon bits from chef Seth Glessner of The Emerson Grill in Bozeman, MT.
