Bake. Put a rimmed baking tray in oven and heat to 400°. Cut leeks in half lengthwise. Rinse well plus pat completely dry. Toss using oil in a big bowl; add salt till it tastes right. Set out leeks, cut side down, on hot baking tray plus cover without sealing using foil. Reduce oven temperature to 300°. Cook till leeks are gently browned on cut side and very tender, around 1½ hours. Uncover leeks plus turn cut side upwards. Increase oven temperature to 400°; roast leeks till a deep gold, 15–20 minutes. (Reserve this oil for making vinaigrettes or roasting vegetables. Leave till it is cold; put a lid on plus put in the fridge.) DO AHEAD: Leeks can be baked 4 hours ahead. Leave till it is cold; put a lid on and put in the fridge. Bring to room temperature before serving.

EU nutrition claims
- Low salt: 0.06 g salt per 100 g (limit ≤ 0.3 g)
Per 100 g of the finished dish, worked out from the nutrition per serving and the lowest likely cooked weight (about 175 g a serving), so the true values are, if anything, lower. Thresholds from the Annex to EU Regulation (EC) No 1924/2006. How we decide
