San Marzano Ketchup

Add a bit of sophistication to your next summer barbecue with this homemade ketchup from San Marzano tomatoes. 


In a pot combine all of the ingredients and cook on medium heat, stirring with and mashing with a whisk as you go, until all tomatoes are broken down and desired consistency is obtained, about 15 minutes. For a smoother finish push ketchup through a china cap or fine mesh strainer. Refrigerate to cool before serving.
