Your instructions were somewhat confusing or incomplete. Your photo shows the final dish after toppings are added. However, you said to coat the whole head with the yogurt mixture and place in center of oven. But, you never mention cutting up the head into separate florets after it’s cooked and placing in a casserole dish. It’s just somewhat confusing the way it is worded. I cooked the whole head of cauliflower in one piece, as I’ve seen other similar recipes use this process. Then after it cooled I broke it into smaller pieces, put in a casserole and put on the toppings. I did rewarm it before serving.
