As if yet, I have not made my own ketsup, but this makes me want to because you get to control the flavors.  Hmmm, am I a control freak?  Perhaps.Â

1 sliced onion

2 sliced tomatoes

2 T balsalmic vinegar

4 T brown sugar

1 tsp Thyme

1 tsp ground black pepper

1 tsp salt    Â

Saute onions until they are translucent, add fresh tomatoes, brown sugar, vinegar, thyme, salt and pepper.

Enjoy
