Three Cheese Macaroni

Don't be scared...it's really good! Ella says it is better than regular Macaroni and Cheese! :)

Ingredients

1 large egg
1 12-ounce can evaporated whole milk
Pinch of cayenne pepper
Pinch of freshly grated nutmeg
Kosher salt and freshly ground black pepper
1 1/3 cups grated muenster cheese (4 ounces), plus 4 deli-thin slices (1 ounce)
1/2 cup grated sharp cheddar cheese (2 ounces)
1/4 cup grated parmesan cheese (1 ounce)
1/2 head cauliflower, cut into small florets (4 cups)
4 cups medium pasta shells (9 ounces)

Directions
Whisk the egg, evaporated milk, cayenne, nutmeg, and salt and black pepper to taste in a bowl. Toss the grated cheeses in a separate bowl.

Bring a large pot of salted water to a boil. Add the cauliflower and cook until almost falling apart, about 7 minutes. Transfer to a bowl. Add the pasta to the same water and cook, about 10 minutes. Drain and reserving 1/4 cup cooking water. Preheat the broiler on high.

Combine the egg mixture and the grated cheeses in the empty pot and cook over medium-low heat, stirring constantly, until the cheeses melt and the sauce starts to thicken. Remove from the heat and add the cauliflower. Move mixture to a blender and puree (you can use an immersion blender but it didn't work as well for me) until smooth. Stir in some of the reserved pasta water until creamy.

Toss the pasta in the sauce; season with salt and black pepper. Transfer to a shallow casserole dish and top with muenster slices. Broil until golden brown, about 5-10 minutes.
