Drop the dry pasta in boiling water. Make sure that the fettucine don't stick to each other by moving them around a lot in the first minute of boiling.
Boil according to the timing on the package, usually 8-9 minutes.
While the fettucine are boiling, in another pot, melt the cream cheese on medium heat and stir until soft and creamy.
Mix the water and the cornstarch together. Gradually add the water/starch to the cream cheese while stirring. Add MSG, salt and pepper.
Garnish with fresh parmesan.
