Let your Veggies Freeze!
Unlike tomatoes and peppers, which turn soft and mushy when they are hit by frost, many vegetables are at their best when they experience a frost or two. This select group of cold-loving vegetables includes cabbage, Brussels sprouts, kale, leeks, parsnips, Jerusalem artichokes, carrots, turnips, and other root vegetables. You can even mulch heavily and leave them under the snow all winter: their taste will be even better in the spring! Under the effect of freezing, these vegetables convert much of the starch they contain into sugar… and we humans find sweet vegetables the tastiest.
