I pronounce it Cha-Cha, but I've seen it in stores as Chow-Chow.
My problem is I can't find a really good recipe for it, and store bought just isn't the same, not even close. No one seems to make it anymore. I haven't tasted it in @ 20 yrs and I miss it. Do any of you remember it? It's crispy, sweet, tart, and pickley.
