Bring water, evaporated milk and seasonings to a boil.
Add macaroni and simmer stirring frequently until the macaroni is tender, 12-14 minutes. Add additional water ¼ cup at a time if needed. Ensure you have liquid in the bottom of the pot to make the sauce.
Once macaroni is tender, remove from the heat and stir in cheese a bit at a time until melted.
Stir in butter and season with salt & pepper to taste.
