Cook angel hair pasta according to directions on the package.
In a large skillet over very low heat, warm the oil and garlic being very careful not to burn or discolor the garlic. Allow the oil and garlic to infuse for 10-15 minutes. Again, be very careful not to burn or even brown the garlic. Simply remove the skillet from the heat if you feel it is too hot and allow to cool slightly for 3-4 minutes before returning to the heat. Fold in the crushed red pepper and the hot angel hair pasta, combining thoroughly. Add a little of the pasta water.
Divide among 4-8 serving bowls and finish each with grated cheese as desired.
