Cook safely

Keep children and pets away from the hob and the oven, and keep oven gloves and a lid within reach.

Boiling water and steam. Turn pan handles inward, away from the edge of the hob. Lift lids away from you, and pour hot water away from your body: steam burns too.
Blending hot liquid. Let it cool a little first, fill the blender no more than a third, and hold the lid down with a folded towel. Start on the lowest speed. A stick blender in the pan is safer.
Sharp knives. Cut on a board that doesn't slip (a damp cloth under it helps), and curl the fingers of the hand that holds the food.

Method

After preparing the leeks, wash them very well in water to remove all traces of dirt and grit, which hide between the layers. Drain well.
Melt the butter in a large pot over medium heat. Add the vegetables, and season with a pinch each of salt and pepper. Stir to coat everything well with butter.
Cover the pot, and let the vegetables sweat over low heat for 10 minutes—make sure not to let them brown.
Stir in the chicken stock, and bring the pot to a boil. Simmer until the vegetables are cooked through.
Working in batches if necessary, purée the mixture using a hand- or full-size blender.
If you would like a very smooth soup, work the puréed mixture through a sieve into a clean pot—this is laborious, but it yields a velvety product.
Taste the soup, and season to taste with additional salt and pepper.
