Step 1

Place a cast iron skillet on the stove over medium-high heat and bring pan juices to a simmer. Add the smashed garlic, crushed peppercorns, fresh thyme, shallot, brandy, beef broth, cream, and lemon zest. Let simmer and reduce, uncovered, 10-15 minutes – whisking fairly often.

Step 2

Once it has reduced and it is thick enough to coat the back of a spoon – remove from heat. Taste and add any salt or pepper, as desired.

Step 3

Combine ingredients in a small bowl. Stir to combine.

Step 4

Taste and add additional prepared horseradish, as desired.
