Tips from the ELLE Gourmet Editors
What are chestnut mushrooms?
Chestnut mushrooms grow as clusters of small cinnamon brown, scaly caps on long white stems. Above all, they are prized for their nutty flavour and crunchy texture that remains even after cooking, making them ideal in soups and sauces. Find chestnut mushrooms online direct from local growers or at specialty grocery stores. Brown cremini or shiitake mushrooms are perfectly reasonable substitutes.
Tips for a smooth béchamel
Béchamel is one of the mother sauces of French cuisine, a white sauce of milk thickened with roux (a paste of flour and butter). It’s the creamy layer of classic lasagna and forms the base of many mac & cheese recipes, soufflés, gratins and creamy casseroles. Fortunately, it’s also very forgiving. The keys to success lie in cooking the sauce over medium-low to medium heat only because you can’t rush a good thing. Whisk and cook the butter and flour together for a few minutes until the paste is smooth and lump-free. This step is crucial in keeping the sauce smooth once the milk is added and cooks out the raw flour flavour. Whisk the milk in slowly, but confidently. Continue whisking until the sauce is smooth and thickened. Add seasoning (salt, pepper, herbs, cheese) at the very end to suit your taste.
