At the Farmers' Market: Kohlrabi
Is there no end to the variety of Brassica plants we can eat as humans? Cabbage (domestic, Savoy and Napa), broccoli, cauliflower, romanesco, Brussels sprouts, all Brassica.
Brassica of Brassicas, all is Brassica--including the odd-looking (but delicious) kohlrabi.
This odd-looking bulb looks like a cross between a beet and an inflamed green (or purple) agave piña, with beet-like greens fleeing the bulb at odd angles. Both the leaves and the bulb are edible, but it's the bulb that is the money here.
As with any leafy root vegetable, the perkier and better the greens look, the better the bulb below is. And as with any leafy root vegetable, the sooner you get the greens separated from the bulb, the longer both will last.
Kohlrabi: the chameleon of the Brassica family.
