January is a grim season for locavores. I try to eat locally whenever I can, but there's no way I'm going to pass up a juicy Pomelo in January or a sweet box of clementines in December. Thankfully, citrus is in season during the winter months, even if it does have a lengthy sojourn on the way here.
If you live on on the West Coast, you have a few more options. Om Organics has a nice chart of what's growing when in the Bay Area.
For those of us out here in the East, things are pretty sparse at the farmers markets. What should you be eating now? Broccoli. Cauliflower. Root Vegetables. Pumpkins. Citrus fruits and all manner of hearty greens.
Eating peak-season produce is a great food resolution because it's cheaper, it's more nutritious and when you buy locally, you support your farming neighbors. And that's just plain old good karma.
I've made up a chart here to keep those of us in the Northeast region on track throughout the year. (Anything that's not grown locally is indicated with an asterisk.)
Apples to Cabbages
Carrots to Grapefruit
Green Garlic to Sweet Onions
Blood Oranges to Wild Ramps
Raspberries to Turnips
