It wa really simple - tomato sauce, vinegar and brown sugar and allspice. That's right - no chili nor pepper goes into that chili sauce recipe. The first time we made it it turned out bland and meh. And there was leftover tomato sauce since there was more than a cup in a can.
The second time around I scaled up everything else to use up the whole can of tomato sauce and according to the suggestions/reviews added more oomph to it with garlic, onion and chili powder. Except that I also don't keep allspice nor chili powder at home. So the final version of my chili sauce recipe went from 4 ingredients to a dozen:
Seems like quite the list but everything is in my little spice caddy so it takes no time at all to throw together. And this we usually use up because we often double or triple the amount of meatballs.
