I saw these on tv, no recipe, but the idea appealed to me straight away. I love cinnamon, so I had to try. Made the macaroons usual way, minus the artificial colouring, but nearly 2,5 tsps of cinnamon went in. I kept on adding until I was satisfied and still managed not to overdo it. The filling took a bramley apple and one pink lady cooked down  to a pulp with some vanilla sugar, mixed with 2 gelatine leaves, then cooled. I wanted the filling to keep its shape and it did quite well, without having a jelly consistency.

The result is a bit like a crunchy apple pie, lovely, warming from the spice, crunchy from the meringue. Good one!
