I’m looking for a children’s story about a princess who couldn’t clap, which embarrassed her family when they went to the opera. At the end of the story, she’s given a pair of gloves that button together at the wrists, so she can enjoy the opera with everyone else. I think there was a mention of something called “jumble mints” or “jumble sweets". It was probably part of a children’s anthology I had in the late 80’s and early 90’s. I’ve been searching for years; nobody in my family remembers this story and I’d be so thrilled to find it!
