Chutney is a good idea!
I found this thread searching for what to do with the one I have. I bought two green at a Mexican market, tried a bit unripe and let one ripen. Smells amazing, and I’m macerating
while I look for something simple. Preserve or jam I think. Or maybe a pickle. Does it change colors with cooking? Yes!
This page has some good ideas.
ETA Oops! Just noticed this was a chutney thread. I was looking for favorite quince recipes. I will link to the jam making thread.
