Fondue de poireauxSlow-cooked leeks in butter
Fondue de poireaux is a winter side from northern France and Belgium, cooked in home kitchens from Picardy to Lille whenever leeks are cheap and sweet. Thinly sliced leeks are sweated very gently in butter with a lid on until they collapse into a soft, pale-green tangle, then finished with a spoon of cream and nutmeg. Serve it with roast fish, eggs, potatoes, or spooned onto toast as a light supper. The usual mistake is cooking over too high a heat, which browns the leeks and makes them bitter; they should never colour. Chef's tip: wash the sliced leeks in a bowl of water and lift them out with your hands, so the grit stays at the bottom.
