This is really good. I wrote a post yesterday on an instant ketchup that is definitely good in a pinch. That got me curious to try Cathy's recipe. It's really good. I thought the apple would make it not taste like ketchup but it's great. I didn't have lemon so I used fancy-pants apple infused balsamic vinegar. I suspect that's even better!
Now the only problem is, it makes more than I need for a day or 2, and what if it gets old before I'm done with it? I decided to divide it into two bowls and freeze one. I'm not sure how it will be after thawing. I'll find out soon enough!
