Key Ingredients and Substitutions
- Cauliflower- You can find this in the produce section of most grocery stores. It tastes very similar to regular cauliflower, but has a slightly stronger flavor.
- Butter (or ghee for Whole30/Paleo/dairy free)
- Prepared horseradish- If you can't find prepared horseradish or don't have any on hand, wasabi would be a good substitute. Start with a little bit and add more to taste. It's a little bit stronger in flavor than horseradish.
- Black pepper
Step 1: Add cauliflower florets to a medium or large saucepan and add enough water to cover the cauliflower. Add a generous pinch of salt to the water, put the pot over high heat, and bring to a boil. Cook the cauliflower until it's tender and easy to pierce with a fork, about 20 minutes.
Step 2: Once the cauliflower is done, drain the water and add the cauliflower back to the pan. Add butter, prepared horseradish, salt, and pepper, and mix until the butter melts.
Step 3: Use an immersion blender to blend the cauliflower until it's smooth. If you don't have an immersion blender, place the cauliflower in a blender or food processor and blend until it reaches your desired consistency.

If your cauliflower isn't quite tender after 20 minutes, just cook it a bit longer. After 25 minutes or so, it should definitely be tender and ready to puree.
