Lori's Cauliflower au Gratin
I love cauliflower and this is one of my favorite recipes. I have been making it for years. The horseradish makes it special. I always add the full 2 tablespoons.
Substitute 1/4 cup chopped onion for the shallot if preferred. Substitute 1 teaspoon garlic powder for the minced garlic if desired.
You can use half-and-half instead of heavy cream to lighten the dish up.
Use a food processor instead of an immersion blender if preferred.
