Step 1

Remove cauliflower florets from tough core. Place in microwave-safe glass dish. I always use my two-qt Pyrex glass measuring bowl. Do not add water. Do not cover.

Step 2

Microwave on HIGH for 10 minutes. Stir and continue on HIGH for 8-10 more minutes until cauliflower is soft throughout. Microwave ovens and cauliflower size vary hugely and will affect cooking times. If you have an older oven it may take several minutes more. A larger than average cauliflower will also take longer. Check often if you are new to this method. A few scorched spots on the cauliflower is not a big deal.

Step 3

Pour steaming cauliflower pieces into a food processor and allow it to sit until the steaming stops. Puree until smooth. Add butter, salt and lots of pepper.
