Chef + cookbook author Sara Moulton's 3-ingredient horseradish sauce can dress up a variety of meat dishes, like her Slow Cooker Braised Short Ribs, or even serve as a delish dipper for potatoes.
Place the horseradish in a small strainer set over a cup and press until the horseradish is quite dry. Measure and set aside 1 tablespoon of the drained horseradish and 1 tablespoon of the liquid. Strain more if you don't have enough.
Whisk together the sour cream, reserved horseradish and liquid, lemon rind, and salt and pepper to taste.
