Classic Béchamel
This is the structural foundation for many gratins and pasta dishes. Master the mechanics of the roux, and you gain control over the texture and consistency of everything from macaroni to creamy vegetable bakes.
Watch your heat and keep whisking.
The difference between a silky sauce and a gritty one is patience; add the milk slowly to ensure the roux incorporates fully before adding more liquid.
- Heavy-bottomed saucepan
- Balloon whisk
- Fine-mesh sieve (optional, for insurance)
What goes in.
- 2 tbspunsalted butter
- 2 tbspall-purpose flour
- 2 cupswhole milk, warmed
- to tastefine sea salt
- pinchfreshly grated nutmeg
Controlling the Roux
Cook the flour and butter for at least two minutes before adding milk to remove the raw flour taste; the roux should smell toasted, like shortbread, but not show any brown color.
The method.
Melt the butter
Place the saucepan over medium-low heat. Add the butter and let it melt completely until it begins to foam.
Cook the roux
Add the flour and whisk immediately. Cook, stirring constantly, for two minutes. It will look like a thick, pale paste.
Incorporate the milk
Pour in about one-quarter cup of the warm milk. Whisk vigorously until the paste absorbs the liquid. Repeat this process until all milk is incorporated, then whisk in the remainder.
Simmer to thicken
Increase heat to medium. Keep whisking until the sauce reaches a slow simmer. The texture should change from liquid to a thick, opaque cream.
Season
Remove from heat immediately. Stir in the salt and nutmeg. If it looks uneven, pass it through a fine-mesh sieve into a clean bowl.
Other turns to take.
Mornay Sauce
Stir in a handful of finely grated Gruyère or sharp cheddar once the sauce is off the heat.
Mustard Béchamel
Whisk in a tablespoon of whole-grain mustard after the sauce has thickened; this pairs well with roasted cauliflower.
When it doesn't go to plan.
Always warm your milk in a separate pot or the microwave; cold milk hitting a hot roux creates stubborn lumps.
Use a balloon whisk to reach the corners of the pan where the sauce tends to settle and scorch.
If you are not using the sauce immediately, press a piece of plastic wrap directly onto the surface to prevent a skin from forming.
The ones that keep coming up.
Why is my sauce grainy?
You likely added the milk too quickly or did not whisk vigorously enough during the initial stages. If it happens, whisking in a small splash of extra warm milk can sometimes smooth it out.
Can I fix a sauce that is too thick?
Yes. Simply whisk in additional warm milk, one tablespoon at a time, until it reaches the consistency you need.
