Homemade Unsweetened Ketchup Recipe

My sister and I were chatting today about how sugar sneaks into nearly everything, including random things like ketchup. I told her to make her own from tomato paste because she likes it on her eggs, but she didn’t have a recipe. Here you go sis! I’ve used this many times.

  1. oh my gosh – I was lamenting just this morning that I don’t have ketchup and that just plain tomato paste smeared on eggs is insufficient. Done. I’m making some tonight to join my kale.
