Try recipes for Membrillo, it is quince cheese a sort of thick marmelade. In Spain they serve it for breakfast with cheese.
Once had it at a hotel where they were having a posh conference so they had everything you could think of and more for breakfast. Membrillo was the star turn. We had no idea what it was, and it was before wifi so no chance of a quick google.
Are we talking about quince or the japanese flowering Chaenomeles which I find them rather hard to peel. They add a different flavour will a couple in an apple crumble.
