Ingredients for Celery-Root Purée with Truffle Butter
1.4kg celery root (sometimes called celeriac
2 large), peeled with a knife and cut into 1/2-inch pieces (1925ml )
800g boiling potatoes (3 large), peeled and cut into 1/2-inch pieces
240ml double cream
110g black truffle butter* or 1 stick (110g ) unsalted butter
1 teaspoon salt
1/4 teaspoons black pepper
How to make Celery-Root Purée with Truffle Butter
Cover celery root and potatoes with cold salted water by 2 inches in a 4- to 6-quart heavy pot, then simmer, covered, until celery root is very tender, about 15 minutes.
While vegetables are simmering, bring cream, truffle butter, salt, and pepper just to a simmer, stirring until butter is melted.
Drain vegetables in a colander and transfer to a food processor. Add hot cream mixture in a steady stream, pulsing until smooth. (Alternatively, mash vegetables with hot cream mixture using a potato masher.)
