It's true what they say: root vegetables only get sweeter when they've been frosted over.
For our cholent dinner over the weekend I foraged carrots and parsnips from the garden. They were planted last spring and have fully grown. I left them in the ground to make their own storage. The soil here in the District of Columbia is only modestly frozen, mostly near the top as a result of below average temperatures, down into the single digits at one point. For the second year in a row, I broke the handle on my forked spade prying the vegetables out of their beds. Last year I broke it trying to bury some kitchen scraps in my frozen compost pile. I have ordered a steel-handled spade.
Cleaning up my carrots and parsnips was somewhat more involved than usual, since the garden hose has been turned off pending a thaw. I have to fill a basin of water in the sink and scrub by hand. They clean up pretty nicely. Then they are peeled, cut on an angle, tossed with extra-virgin olive oil, salt, pepper and thyme and roasted in a 325-degree oven.
I swear, you will not find better root vegetable on any menu.
