Course: Sauce
Cuisine: French
Prep Time: 2 minutes
Cook Time: 15 minutes

Equipment

  • Saucepan (Option 1)
  • Pot (Option 2)
  • Whisk

Ingredients

  • 25 gram Butter
  • 40 gram Wheat Flour
  • 515 gram Whole Milk
  • Salt and Pepper
  • Nutmeg grated, a little
  • 40 gram Grated cheese
  • 1 pcs. Egg Yolk can be omitted
  • 5 gram Dijon Mustard can be omitted

Instructions

  • Start by putting the butter in a small pot/saucepan and melt it.
  • I usually set it to 9 or 10 on my stove.
  • Add flour to the pot and whisk it well. Keep at it until you have a smooth paste and let the process take 2-3 minutes to ensure the flour is well cooked through, so it doesn't taste like flour.
  • Add 1/3 of the milk and whisk it well. Don't start too hard, or you'll splash it all over the kitchen (speaking from experience :-)).
  • Gradually add the rest of the milk while stirring it well. The goal is to eliminate all lumps, and the sauce should thicken.
  • Season with salt, pepper, and grated nutmeg.
  • When the sauce tastes just right, turn off the stove and let it sit for 30-60 seconds.
  • Add the grated cheese (and mustard if you like) and stir it well into the sauce. If the burner is still on, there's a chance the cheese will become stringy.
  • The sauce should have thickened quite a bit; if it's too thick, just add a little milk.
  • If you want the sauce to be even creamier, add an egg yolk and whisk the sauce for another minute.
  • Enjoy.
