Looking for a simple side that’s light and fluffy but not mashed potatoes? This Cauliflower Purée is airy and delicate, a blend of cauliflower and celery root. One potato is added to the mix for a touch of heft and a little starch to prevent the purée from becoming a thick soup. The result is a refined side dish that is a wonderful accompaniment to fish, meat and winter stews.
The celery root, also known as celeriac, is mildly redolent of celery, and nicely balances the nutty and sweet notes of the cauliflower. Serves 6-8 as a side dish.
1 large head of cauliflower, chopped in 1 inch pieces
1 medium celery root, peeled, chopped in 1 inch pieces
1 large russet potato, peeled, chopped in 1 inch pices
Bouquet garni: 3 thyme sprigs and 1 bay leaf tied in cheesecloth
1 garlic clove, chopped
1/4 cup unsalted butter, cut in large pieces
1/2 cup sour cream
1 teaspoon salt
1/2 teaspoon freshly ground black pepper
1/4 teaspoon ground nutmeg
Thyme sprigs as garnish
Combine cauliflower, celery root, potatoes and bouquet garni together in a large pot. Cover with water. Bring to a boil and simmer, covered, until all of the vegetables are very tender. Drain and discard bouquet garni. Transfer to a food processor. Add garlic and butter and purée until smooth. Add remaining ingredients and pulse to blend. Taste for seasoning. Transfer to a serving bowl. Serve warm, garnished with thyme.
