Better Than Mashed Potatoes Celery Root Purée

Celery root may be one of the homeliest vegetables in season right now, and probably takes the cake for the ugliest vegetable all year round. But this vegetable, which is also known by the name of celeriac, does a tremendous job of adding panache and elegance to creamy soups, salads and purées. With a pat of fresh golden butter and cream, the concentrated flavors of celery can be coaxed and tamed into a sublime nostalgic mashed potato-like concoction - flavors that are familiar but intriguing with hints of parsley and sweet parsnip nuances that will keep guests guessing.

One of my favorite ways to prepare this vegetable is to create a purée, that I personally prefer over traditional mashed potatoes for its light creamy and silky texture and complex herb hints. This purée is excellent served with spicy curry or roasted lamb.

If you are in New York City, celery root is available at Gorzynski Farms and Keith's Farms at the Union Square Farmers Market every Saturdays. Celery root can also be found at most Whole Foods Markets across the country.  To pick a celeriac, choose one that is heavy for its size, and void of any soft spots. Celery is listed among the dirty dozen, the twelve fruits and vegetables that retain the highest level of pesticide residue, so it if you can, it may be worthwhile to seek out a pesticide-free source.
