Ingredients:
- 2 tbsp Unsalted Butter
- 2 tbsp All Purpose Flour
- 1/4 tsp Sea Salt
- 1.5 cups Whole Milk
Instructions:
- In a heavy-bottomed saucepan over medium heat, melt the unsalted butter until foaming. Whisk in the flour and sea salt, cooking for 1-2 minutes until the mixture smells nutty and resembles wet sand, without browning.
- Slowly pour in the room-temperature whole milk, approximately 1/4 cup at a time. Whisk vigorously after each addition to prevent lumps. Continue to cook and whisk for 4-5 minutes until the sauce is thick enough to coat the back of a spoon.
- Remove the saucepan entirely from the heat source.
- Gradually fold in the cheese until it melts into a smooth, glossy emulsion.
