Medlars are also mentioned in Amahl and the Night Visitors, along with a host of fruits the shepherds and villagers are taking to the visitors. I always wondered what a medlar was. Thank you for clearing that up.
Now, what are mignonettes (from the same song in the same play)? ^_^
Ah - googled it. Found no edible fruit, just lots of fragrance, and this: It was used as a sedative and a treatment for bruises in Roman times. I'll just have to guess that this was medicinal for those visitors. Or that the writer had no idea what he was talking about.
