Ingredients:
- 16 oz Lumaconi or Medium Shell pasta
- 4 quarts Water
- 2 tbsp 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 cheddar cheese, freshly grated
- 2 oz White American cheese, chopped
- 1 tsp Dry mustard powder
- 1/2 tsp Salt
- 1/4 tsp White pepper
- 1/4 tsp Hot sauce
Instructions:
- Add 16 oz Lumaconi or shells and cook 8-10 minutes until al dente with a slight bite. Drain the pasta but do not rinse it; the surface starch helps the sauce stick.
- In a medium heavy-bottomed saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1-2 minutes until it smells slightly nutty but remains pale.
- Slowly drizzle in the whole milk and heavy cream, whisking constantly to ensure no lumps form. Simmer gently until the sauce thickens enough to coat the back of a spoon.
- Whisk in the dry mustard powder, 1/2 tsp salt, white pepper, and hot sauce.
- Reduce heat to low. Gradually stir in the freshly grated white cheddar and chopped American cheese, whisking continuously until the sauce is smooth and the cheese is fully emulsified.
- Fold the cooked pasta into the cheese sauce until every shell is thoroughly coated. Serve immediately.
