FAQ
How much dry pasta is one serving?
The standard Italian main-course portion is 80 g of dry pasta per person — about 160–170 g cooked. For a first course or a side, 60 g is plenty; big appetites want 100 g.
How much does pasta grow when cooked?
Dry semolina pasta absorbs water and roughly doubles in weight; a 2.05× multiplier is a good planning figure. Fresh egg pasta and filled shapes contain egg and moisture already, so they gain only about 50%.
Why so much boiling water?
A large volume of water drops less in temperature when the pasta goes in, so it returns to a boil fast and the starches dilute instead of making the pasta gummy. One litre per 100 g is the classic rule.
