A DIY recipe for horseradish vodka can be found in Kachka: A Return to Russian Cooking, the award-winning cookbook Bonnie Frumkin Morales co-wrote with journalist Deena Prichep in 2017.
The recipe calls for the horseradish to steep for one week in the vodka, imparting a rich and bracing burn to the alcohol. “It wakes you up,” Frumkin Morales said. “It is really energizing.”
Place the horseradish root in a quart-sized mason jar and pour the vodka over it. Reserve the vodka bottle for the finished product. Screw on the lid and let steep for 1 week in a dark, cool place.
After steeping, carefully pour the honey into the reserved bottle. Strain the vodka from the horseradish into the bottle using a fine-mesh strainer and funnel. Discard the horseradish. Close the bottle and shake to combine. Freeze for at least 1 hour before serving.
