Before you start

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)
Ingredients

What goes in.

  • 2 tbspunsalted butter
  • 2 tbspall-purpose flour
  • 2 cupswhole milk, warmed
  • to tastefine sea salt
  • pinchfreshly grated nutmeg
The key technique

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.

Step by step

The method.

  1. Melt the butter

    Place the saucepan over medium-low heat. Add the butter and let it melt completely until it begins to foam.

  2. Cook the roux

    Add the flour and whisk immediately. Cook, stirring constantly, for two minutes. It will look like a thick, pale paste.

  3. 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.

  4. 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.

  5. 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.

Variations

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.

Tips & troubleshooting

When it doesn't go to plan.

Tip

Always warm your milk in a separate pot or the microwave; cold milk hitting a hot roux creates stubborn lumps.

Tip

Use a balloon whisk to reach the corners of the pan where the sauce tends to settle and scorch.

Tip

If you are not using the sauce immediately, press a piece of plastic wrap directly onto the surface to prevent a skin from forming.

Questions

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.
