    Cook’s tip

    A classic Bechamel or white sauce is the base for many dishes. The key to getting it right is to mix equal quantities of melted butter and flour together, cook for a minute, then gradually add milk making sure the mixture is smooth. Add more milk, return to the heat and stir until the sauce simmers and has thickened.
