Preheat the oven to 400 degrees F.
Prepare the pasta according to the directions on the box given for al dente pasta. Drain the pasta and put back in the same pot over low heat. Add the half-and-half, half the Cheddar, the pimento cheese and habaneros. Stir until melted and creamy. Stir in the mustard, salt and pepper. Pour into a 9 by 13-inch casserole dish, top with the remaining Cheddar and sprinkle with cayenne pepper. Bake until golden brown and bubby, about 20 minutes.
Cook's Note: I use sharp Cheddar mostly, but you can you use any mixture of cheese you have on hand. There is no wrong cheese for this recipe.
