soft. Add the stock, and season with a little salt and pepper. Bring to the
boil, reduce the heat and simmer gently for 30 minutes. - Stir in the milk and heat through.
- Whisk the egg yolks with the lemon juice. Add 2 ladlefuls of the hot

heat through gently, still stirring, until slightly thickened. Do not allow the
soup to boil or the egg will curdle. - To make the croûtons, spread out the bread cubes on a baking tray, and

croûtons just before serving.
