Bring a pot of salted water to a boil and add the pasta. Cook until al dente. Drain well and keep warm. Meanwhile, combine the garlic, Gorgonzola, butter, and cream in the top of a double boiler over simmering, not boiling, water. Stir frequently until the cheese begins to melt. Combine the cheese sauce and pasta. Toss well to coat the pasta in the sauce. Season to taste with salt and pepper. Serve warm. You can also substitute goat cheese for the Gorgonzola.
