Homemade Tomato Relish

This is a very traditional tomato relish, similar to the kind your grandmother might submit for the competition at your local fair or show. The only real tweak is the addition of sumac which brings a lightness as well as a slight textural element.
This is a great way to make use of leftover tomatoes. Its a tangy dressing, you can use it anywhere you might use ketchup for a slightly more refined flavour.
