Science Channel's popular series How It's Made answers that question and gives us a look at the ketchup-creating process. In it, we see the dry components used to make the red tomato-based paste as well as the mixing process with the wet ingredients. Because it's all in bulk, and not made in a kitchen, the operation is pretty captivating to see.
Everything is then bottled, packaged, and shipped off to stores.
If you love slapping ketchup on food like we do, (scrambled eggs, anyone?) you might get a kick out of seeing how the condiment is mass-produced.
