Alternately, steam the cauliflower, drain/press it dry well, and “mash” it in a blender or food processor with cream, butter, salt and pepper. My family likes mashed cauliflower better than mashed potatoes now and I always use frozen cauliflower.
I thought we were the only ones who did that - my kids LOVE cauliflower "mashed potatoes" but any time I've mentioned it to my friends, they react with disgust. We use steamed fresh cauliflower though.
