50 g butter50 g all-purpose flour500 ml milkSalt • • Nutmeg
Instructions
Melt the butter in a heavy-bottomed saucepan over low heat (photo 1).Once the butter has completely melted and starts to bubble gently, add the flour (photo 2). Whisk continuously until the flour is fully incorporated into the butter and no lumps remain (photo 3).
Gradually pour in the warm milk in a thin stream (photo 4), whisking constantly. Continue cooking the sauce over low heat, stirring continuously, until it thickens (photo 5).Season with salt and add a generous pinch of nutmeg (this is essential!).
Cover the sauce with a lid if you are not using it immediately. Otherwise, a skin will form on the surface and may create lumps when the sauce is reheated or mixed into other dishes.
