Spaghetti Tester & Steam Releaser. Al Dente casts a line or two into the pot to reveal whether your spaghetti is ready or not. The spaghetti tester is a tool that should not be missing in your kitchen! Ideal, you cook your spaghetti in the pan as you always do, but you put fisherman Al Dente on the edge of your pan and pin a string of spaghetti to it. It holds the spaghetti string well and so you can easily see when your spaghetti is fully cooked. In addition, it also ensures that the steam can leave your pan properly so that the pan does not boil over!
