Step 2

I like to serve 4 or 5 baby leeks per person, depending on their size. Lightly trim both ends and peel back the first or second layer of leaves and discard. Drop the leeks in a pan of boiling salted water for 2 to 3 minutes to soften - this is called blanching. Drain them well (if there's too much water in them they won't roast properly) and toss in a bowl with a good lug of olive oil, a splash of red wine vinegar, the chopped thyme leaves and the garlic. Arrange the leeks in one layer in a baking tray or earthenware dish and roast in the preheated oven for about 10 minutes until golden and almost caramelized. Keep your eye on them - I've seen many chefs burn baby leeks when cooking them this way and it drives me mad!
