This simple recipe yields a classic horseradish cream sauce by combining sour cream, fresh grated horseradish, Dijon mustard, white wine vinegar, salt, and pepper. It requires minimal effort and a significant chilling period to allow the flavors to develop and harmonize, resulting in a perfect accompaniment for meats or a flavorful dip.
For the best flavor and potency, use fresh horseradish roots and grate them just before mixing. The 'heat' in horseradish is volatile and dissipates quickly once exposed to air. Ensure all ingredients are well combined for a smooth texture. Chilling is crucial as it allows the flavors to meld and the sauce to thicken slightly. This sauce pairs wonderfully with roasted meats like prime rib or beef tenderloin, or even as a tangy dip for vegetables.
