Cauliflower lasts much longer than you think if you have space for it in the fridge.
Ideas for what to do with it:
• Have you tried microwaving cauliflower florets with butter (2-3 minutes with a generous slab of butter, then shoogle, then another 2-3 minutes and then season)
• roasted cauliflower florets (try with a pinch of cumin and coriander)
• cauliflower soup
• cauliflower mash with an egg, cream/yoghurt, some cooked thinly sliced leeks (apparently this makes it more potato mash like - although I've not tried it myself but I trust who has advised that ) , Parmesan, all blitzed together
• cauliflower "rice": blitz raw cauliflower to wee bits, then sauté in a generous amounts of butter with extra seasonings of your choice
I like cauliflower
and eat a lot of it while I'm on Mumsnet BootCamp (High Fat Low Carb).
