When I was a kid stewed quinces appeared as a dessert each autumn. We didn’t have a quince tree so I’m guessing Mum was given them by a friend. Like most stewed fruit, Mum served them with a custard and ice cream, they needed a sweet topping as they were a bit tart. You don’t seem them around much these days, the only mention of quinces seems to be quince paste. If you do find some they’re worth trying out, either with spices like this recipe or stewed.
