How do I know when pasta shells are cooked?
The only way to know if it’s done is to taste it! It should be al dente, or firm to the bite. The more pasta cooks, the gummier it gets, so if it sticks to the wall it’s probably overdone. Rinse pasta after cooking and draining.
How long does thick pasta take to cook?
For authentic “al dente” pasta, boil uncovered, stirring occasionally for 11 minutes. For more tender pasta, boil an additional 1 minute.
