It's a puffy baked pancake with sliced apple compote on top. Google it to see what it looks like and get the recipe.
It's the best thing you've never had! Seriously! If you've never had one then you need to try it. It's hard to explain what it is without having to Google it and show you but even then, you'll want to actually try it to experience it.
