What To Do
1. Boil pasta: Cook fettuccine in salted water until al dente; reserve 1/2 cup of pasta water and drain.
2. Make the sauce: In a large skillet, melt butter into the heavy cream over medium heat until it begins to simmer.
3. Whisk: Gradually add the shredded Hatch Chile Cheddar, whisking until the sauce is thick and smooth.
4. Toss: Add the pasta to the skillet and toss to coat. Use the reserved pasta water to loosen the sauce if needed.
5. Finish: Season with plenty of black pepper and serve immediately.
