I tried the size of a quarter and a juice bottle with a long neck. When I cook half of what I measure as 2 ounces it is enough for me. Two ounces according to the quarter theory makes a mountain of pasta. I am thinking maybe there is a difference between the pasta size? The thin spaghetti has a smaller diameter and maybe a handfull that has the diameter of a quarter is 3 ounces not 2 ounces.

Does anyone know.I didn't want to but I guess I need to buy a scale.
