In a large 10-12 inch deep skillet, add in stock, garlic, salt and pepper. Add pasta to pan, breaking in half if need be.
Turn the heat to high, and once the mixture comes to a boil, reduce heat to simmer (medium heat). Add in milk, butter, and nutmeg to sauce.
Cook for 6 to 7 minutes, stirring frequently to coat pasta in liquid.
Once pasta is tender, remove from heat.
Add in freshly grated Parmesan cheese and toss well.

Notes
While cooking the pasta, if the liquid begins to evaporate before the pasta is cooked through, add in 1 tablespoon of milk at a time.
Feel free to break the pasta in half to fit in a pan or to be easier to stir around in the sauce.
Freshly grated nutmeg is best for Alfredo sauce, as it deepens the sauce. Pre-gated nutmeg is NOT the same--just omit the nutmeg from the sauce.
Freshly grated Parmesan cheese is best, as it will give this Alfredo Sauce the best flavor.
This pasta dish is best served fresh. If you happen to have leftovers, store in the refrigerator for up to 3 days. And to reheat add a bit more stock to thin it out, as the pasta may dry out as it sits.
