This is one of those recipes you just can't make once: that's to say, after the first time, you're hooked. It is gloriously easy: you just put everything in the roasting dish and leave it to cook in the oven, pervading the house, at any time of year, with the summer scent of lemon and thyme - and of course, mellow, almost honeyed garlic. I got the idea of it from those long-cooked French chicken casseroles with whole garlic cloves and just wanted to spritz it up with lemon for summer. The wonderful thing about it is that you turn the lemon from being a flavouring to being a major player; left in chunks to cook slowly in the oven they seem almost to caramelise and you can eat them, skin, pith and all, their sour bitterness sweetened in the heat.
