This Pineapple Buckle is a yellow cake with chunks of pineapple mixed in and hints of lime zest and juice, and after some time in the oven slices of pineapple are arranged on top. Because the batter has been partially cooked, the slices won't sink in and will sit on top, pretty as a picture. That's what the recipe said, anyway. What happened is another matter.
