I made a batch this morning. I wanted to mention that in that video clip, the chef fills the cups full and this has never, ever worked for me. I do use a very fresh baking powder so mine rise pretty quick. When I fill the cup to the top, I get the same deal as if I were to fill a muffin cup full as it comes out and in this case since you must turn them, it is a mess. I use a paring knife to turn them and if one spot is sticking I try a different area and they usually come right up. Mine often have a hollow in the center and don't look like a beautiful ball but that hole is great filled with preserves and it is easier to tell if they are done in the center. Don't expect perfect results but despite how they look, they are always tasty! Also, I add spices like nutmeg, cinnamon and cardamon to the batter and you could also add things like lemon or orange peel.
