Open the can of San Marzano tomatoes using your can opener. Pour the tomatoes into a mixing bowl, and crush them with your hands or use a blender for a smoother sauce.
Add your chiffonade basil leaves to the tomatoes for flavor infusion.
Sprinkle the sea salt over the mixture and gently combine all the ingredients.
Taste the sauce and adjust seasoning if necessary. Remember, the beauty of homemade sauce is the ability to customize!
Let the sauce sit for at least 30 minutes before using to allow flavors to meld.
