Uh oh... Mom forgot to add ketchup to the grocery list! Forget about going back to the grocery store on a Saturday, and to hell with paying $6+ at the local convenience store.
Gather your supplies.
Stir all of your ingredients together except the water. Bring to a boil and then add enough water to reach your desired consistency.
Be an ass and pour it into the empty ketchup bottle and don't tell anyone.
Give it a shake, store it in the fridge and see if anyone notices the difference.
Now you actually have a good base for other add ins. Get creative! We're up 1/3 of ketchup for about 50 cents. I just might stop buying ketchup altogether!
