Ingredients:
- 1 lb Lumaconi or Pipe Rigate pasta
- 2 tbsp Kosher salt
- 1/4 cup Unsalted butter
- 1/4 cup All-purpose flour
- 2 cups Whole milk
- 1 cup Heavy cream
- 8 oz Extra-sharp White Vermont Cheddar, freshly grated
- 4 oz White American cheese, chopped
- 1/2 tsp Dry mustard powder
- 1/4 tsp Onion powder
- 1/8 tsp Ground white pepper
- 1/2 tsp Salt
Instructions:
- Bring 4 quarts of water and 2 tablespoons of kosher salt to a rolling boil in a large pot. Add the pasta and cook for 1-2 minutes less than the package directions until 'al dente'. Drain the pasta and set aside; do not rinse.
- In the same heavy-bottomed pot over medium heat, melt the unsalted butter until it begins to foam.
- Whisk in the all-purpose flour and cook for approximately 2 minutes, stirring constantly to create a blonde roux that smells slightly nutty. Do not let it brown.
- Gradually whisk in the whole milk and heavy cream, ensuring no lumps remain. Continue to whisk over medium heat until the sauce thickens enough to coat the back of a spoon.
- Reduce heat to low. Stir in the dry mustard powder, onion powder, ground white pepper, and 1/2 teaspoon of salt.
- Add the grated white cheddar and chopped American cheese. Stir gently until the cheese is completely melted and the sauce is velvety and smooth.
- Fold the cooked pasta into the cheese sauce, ensuring every shell is well-coated. Serve immediately while hot.
