Im good at cooking stuff but pretty new to freezing. I want a cauliflower cheese with breadcrumbs on top. Do I cook, mix with sauce and then freeze when cool (or do I wait ot it is cold). I was going to put breadcrumbs on top when I cooked it. Can I could it straight from frozen or does it need to be defrosted first? Should I freeze it in a pyrex dish so it could go straight to oven in that case or in a plastic one and defrost it and then put it into something else to cook. Gosh I making this complicated. but want to have gammon, mash, cauli cheese for a meal in between xmas and new year and trying to be organised rather than cooking on the day as I usually do.
