Down & Dirty: Parsnips

Every week we get Down & Dirty, in which Nozlee Samadzadeh breaks down our favorite seasonal fruits, vegetables, and more by the numbers.

Parsnips aren't the most welcoming vegetable -- after all, they look like carrots after an attack by Bunnicula! But strip away that winter-toughed peel and you're left with a white vegetable that's gently sweet and almost honey-like when cooked.

It's easy to forget that parsnips are cousins to some of the most popular vegetables -- carrots, parsley, celery, dill, fennel, and yes, parsnips, are all members of the plant family Apiaceae. According to the book Domestication of Plants in the Old World by Daniel Zohary, Maria Hopf, and Ehud Weiss, ancient Romans even used the same name, pastinaca, for both carrots and parsnips!

In the kitchen, you can certainly replace parsnips for carrots in many recipes for a milder, more subtle result. For roasting and mashing, however, parsnips are interchangeable with root vegetables from the Brassica family like turnips and rutabagas. But enough about substitution -- it's the parsnip's turn to shine.

1. Notes from the Underground: Parsnips are roots, so they get plenty dirty and knobbly during their months in the ground. (Especially when shopping at the farmer's market, be sure to scrub them!) The secret to parsnips' sweetness is in their time underground, as well. They aren't ready to harvest until two weeks or so after the first frost, when the cold snap of weather converts the starches in the parsnips into sugars.

In fact, you can leave parsnips in the ground all winter long without a problem -- just be sure to harvest them before spring, when, as the University of Illinois Extension tells us, new leaf growth turns the parsnip root bitter and woody.

2. Carrot Top: You'll rarely see them, but parsnip greens look just like carrot greens! If you ever find a bunch with their tops on at market, try these tips from Aki Kamozawa and H. Alexander Talbot of Ideas in Food.

3. Parsnips Unmasked: Because parsnips stay in the ground for so long, their skin grows tough and thick. Peel parsnips before cooking them, whether you're making parsnip fries, dicing them for a chicken soup, or steaming them for a mash.

4. Peels: But don't toss those peels! Just like you'd save carrot and potato peels in the freezer for soup on a rainy day, hold on to your parsnip peels to make rich, fragrant vegetable stock.

When it comes to winter vegetables parsnip is ever the bridesmaid, never the bride, but try out these dishes in which it plays a supporting role. (Especially the potato and parsnip mash that tops the shepherd's pie -- you may never make simple mashed potatoes again.)
