Medlar fruit

I saw these weird fruit in Brussels and bought 2 of them. But they were hard so I carried them for a few days till they got soften. I ate them like a fruit. They are dry but very sweet, perfect for making jams. In Amsterdam, I also saw a Medlar tree in someone’s backyard.

“Medlar fruit are very hard and acidic. They become edible after being softened ("bletted") by frost, or naturally in storage given sufficient time. Once softening begins, the skin rapidly takes a wrinkled texture and turns dark brown, and the inside reduces to a consistency and flavour reminiscent of apple sauce. They can then be eaten raw, often consumed with cheese as a dessert, although they are also used to make medlar jelly and wine."
