Whipped Horseradish Sauce

Cooks at Alfred's Steakhouse, in San Francisco, prepare horseradish by whirring small chunks of peeled horseradish root in a food processor with just enough Champagne vinegar to moisten. Store-bought prepared horseradish is fine, but isn't as fluffy and fresh-tasting. The sauce is terrific with grilled steak.
