Step 1

Cook cauliflower: Place cauliflower in a large pot and cover with water and 1/2 teaspoon salt. Boil until buttery-tender. Drain very well. Place back in the pot over medium-low heat. Stirring from time to time (don't burn it!), steam off all the excess water (about 3-4 minutes). Take off the heat.

Step 2

Make the mash: Place the cauliflower in a large food processor with the blade attachment. Add all other ingredients and process until thick and smooth.

Step 3

Serve warm topped with extra butter and chives, if you like.
