 Straight vinegar or some vinegar of your choice. Apple cider vinegar would be where I'd go, yeah. I found at Sprouts, this is a complete sidebar, I found at Sprouts a peach cider vinegar. I was at Sprouts this week and I saw that. I went, ooh, this looks really good. So something like that. Or you could use something like dill pickle juice. Right. Which is kind of that classic smash burger sauce, has a little bit of dill pickle juice in it.
