This sauce is usually served with a big, juicy steak for good reason: The pairing is magical. But that doesn’t mean it’s not delicious in other applications. Try it on a baked potato, as a sauce for shrimp, drizzled over roasted asparagus, or as a substitute for mayonnaise.
Place heavy cream in a medium bowl and whisk until the cream starts to hold a line when you drag the whisk through it. Using a rubber spatula, fold in crème fraîche or sour cream, horseradish, chives, and salt. Season with pepper and additional salt as desired. Serve with Grilled Prime Rib or smear on a roast beef sandwich.
