Loved the end result, but ... didn't boil the cauliflower since it tends to hold water so well. I put it in the microwave with a couple of tablespoons of water and it came our perfectly cooked and "dry". Alternately, next time I make this I am going to roast the cauliflower which should give it a heartier taste. The other thing that I noticed was that I didn't need to continue cooking the sauce after the cheese melted, it was already thick.This is a great recipe, my granddaughter and I really enjoyed it!

Have made this a few times and it’s always delicious however mine always seems to have a layer of grease to it. At one point the cheese is nice and thick but then breaks down. It’s still sooo good but doesn’t look the most appetizing. Any ideas what I’m doing wrong?
