Has anyone ever made their own ketchup from tomato paste or tomato sauce?

32. EmmyMade did some taste testing

of old Civil War era recipes and found both the northern and southern recipes vastly superior to the stuff in the bottles and fast food packs. I know I've never liked the store bought stuff because they load it up with so much vinegar that it's hard to taste anything else.

Emmy started with tomatoes from her garden. Most of the recipes I've seen that look decent use canned tomatoes, not tomato paste. This one is especially easy: https://www.allrecipes.com/recipe/232397/homemade-ketchup/ I have to say I'd use half an onion and a couple of cloves of garlic instead of the powder, but that's just how I roll. Note that this is a weekend thing, it's an all day cooking process, just wander into the kitchen periodically to stir it so it doesn't burn on the bottom.

The inescapable all day process is likely why bottled ketchup became so popular.
