Quick cooking notes

  • Core ingredients include unsalted butter, fine salt, whole milk, ground nutmeg.
  • Follow all 8 steps in order for the intended texture and doneness.
  • Ingredient quantities listed below are for 4 servings.

Ingredients

  • 3 tbsp unsalted butter (cut into small pieces)
  • 0.5 tsp fine salt
  • 2 cups whole milk (cold)
  • 0.0625 tsp ground nutmeg (freshly grated if possible)
  • 0.125 tsp ground white pepper
  • 3 tbsp all-purpose flour

Instructions

  1. Place a 2-quart heavy-bottomed saucepan on the counter and add 2 cups cold whole milk, 3 tbsp unsalted butter, 3 tbsp all-purpose flour, 0.5 tsp fine salt, 0.125 tsp ground white pepper, and 0.0625 tsp ground nutmeg.
  2. Set the saucepan over medium heat and whisk constantly with a balloon whisk for 2 minutes, scraping the corners of the pan so the flour disperses evenly and no dry pockets remain.
  3. Continue heating over medium heat for 3-4 minutes, whisking steadily, until the butter melts completely and the mixture begins to steam around the edges without boiling.
  4. When the first small bubbles appear at the edge of the saucepan, reduce the heat to medium-low and whisk for 2-3 minutes, until the sauce thickens enough to coat the back of a spoon.
  5. Switch to a silicone spatula and cook over medium-low heat for 1-2 minutes more, stirring across the bottom and sides of the saucepan, until the sauce is glossy and leaves a brief trail when the spatula is drawn through it.
  6. Check the texture by lifting the spatula; the béchamel should fall in a smooth ribbon and have no floury taste. If it tastes floury, cook over low heat for 1 additional minute while stirring constantly.
  7. Remove the saucepan from the heat and whisk the sauce vigorously for 30 seconds to smooth the texture and release excess steam.
  8. Use the sauce immediately, or press a piece of parchment paper directly on the surface and keep it warm off the heat for up to 15 minutes, whisking again before serving.
