Not Your Bottled Ketchup

(shown served with 1 oz "Sliders")
2 pounds fresh, ripe tomatoes
1 small white onion
6 peppercorns
1 tsp dried thyme
1 tbs brown sugar
1 tbs white vinegar
1 tbs extra-virgin olive oil
kosher salt/fresh ground pepper
Coarsely chop tomatoes and onion. In a medium pot over low heat, cook tomatoes and onion together with peppercorns and thyme. Stew until thoroughly softened. Using the back of a soup ladle, push mixture through a sturdy sieve. Discard solid matter. Return liquid to pot and place over medium-low heat. Add brown sugar and vinegar. Simmer for 45 minutes or longer, until mixture thickens to desired consistency (will be somewhat thinner than bottled brands). Add olive oil. Season with salt and pepper to taste.
