Fifteen Kilograms of Imperfect Lemons

This is a spice free version.

Break a large cauliflower into florets and roast with olive oil for 30 minutes. Meanwhile heat 500ml milk, 4 tablespoons plain flour and 50g butter in a small pan and whisk until the butter melts and the sauce is thick. Pour over the cauliflower and top with 100g grated cheese (I used cheddar).
