21/4 cups finely grated Parmesan cheese, divided
1 teaspoon coarse salt
1 cup elbow macaroni (uncooked)
2 cups heavy cream
1 cup grated extra-sharp white cheddar cheese
1 cup grated Cotswold cheese
1/4 cup finely chopped fresh parsley
Heat a medium nonstick skillet over medium heat. Lightly coat it with nonstick spray and then add 1 tablespoon of the grated Parmesan, using the back of the spoon to spread the cheese mound into a thin circle. Repeat twice, so you have 3 cheese rounds cooking at once. Once the cheese is golden, after about 2 minutes, use a small spatula to carefully flip it over. Cook the other side until golden, about 20 to 30 seconds, and then immediately transfer the rounds to mini tart pans or other small molds, such as small glass ramekins.
Press a second tart pan or small ramekin on top of the first to mold the cheese rounds into a cup shape. Cool for a few minutes, then lift off the top pan, remove the Parmesan cup, and set aside. Repeat making cheese cups until you have 24 (this will take about 1 cup to 1¼ cups of the Parmesan cheese. Be sure to reserve 1 cup of the grated Parmesan for the macaroni and cheese).
Bring a large pot of water to a boil. Add the salt and macaroni and return to a boil. Cook, following the package instructions, until the pasta is al dente. Drain and set aside.
While the macaroni is cooking, make the cheese sauce. Pour the cream into a large heavy-bottomed saucepan and simmer gently over medium to medium-low heat (be careful so the cream doesn’t bubble up and out of the pan) until it is reduced by half, 20 to 30 minutes. Reduce the heat to low and add the cheddar, Cotswold and the remaining 1 cup of Parmesan cheeses; whisk until the sauce is completely smooth. Stir in the cooked macaroni and remove from heat.
