1 pound turnips, peeled and cut into 1/2-inch pieces
1 pound potatoes, peeled and cut into 1/2-inch pieces
4 cloves garlic, peeled
3 tablespoons butter
2 tablespoons sour cream or plain yogurt
Salt and pepper
In a large pot of salted boiling water, cook the turnip, potato, and garlic for 10 minutes, or until the vegetables are tender. Drain and puree the vegetables and garlic through a food mill. (A food processor is not recommended, as it can turn potatoes very starchy.) Beat in the butter and sour cream and season with salt and pepper.
