Ending2: [substeps] It's okay if the water comes out slightly dry after you've filled the pot. Allowing the water to boil on high heat, will prevent the pasta from sticking together when ready to cook. Ending3: [title] Add 1.2 ounces (34 g) of salt to the water. [step] You can use kosher or coarse salt. Ending4: You can also place it on the stove over medium heat to help the water separate if needed.
