Equipment

  • saucepan
  • whisk
  • kitchen scale or measuring cups and spoons

Ingredients
  

  • 85 g unsalted butter 6 tbsp
  • 250 g sourdough starter 1 cup
  • 976 g whole milk 4 cups
  • 1 tsp salt
  • ½ tsp black pepper
  • a pinch freshly grated nutmeg

Instructions
 

  • Place a small saucepan on the stove over medium heat and add the butter and heat until it's completely melted.
  • Next, whisk in the sourdough discard. It forms a thick paste as it heats up.
  • Reduce the stove to low heat while stirring constantly and cook for 2 minutes.
  • Be sure to cook the flour mixture for 2 minutes, otherwise, there will be an uncooked flour taste in the sauce.
  • Add half of the milk and whisk until it's incorporated well. Then add the remaining milk and continue to whisk over low heat until the sauce is silky smooth and coats the back of the spoon.

Storage

  • Make the sauce as directed and transfer to a storage bowl. While it's still hot, press a piece of plastic wrap directly on the top of the sauce. Without the plastic wrap, the sauce will form a skin on top as it cools.
  • To reheat, warm the sauce on the stove over low heat. Whisk in additional milk to thin if needed.
