The shapes are of good stable quality; they fit side by side in the oven - very convenient. Have you already tried and was with the result, cute little Savarins (or mini-donuts), very satisfied. Since I use in such forms greaseproof Spray (and among other things a lot of time saving up for greasing's), the baked goods popped out just so, not crumble or break. Unfortunately no prescription proposal is, but I have my own tried and the result was very tasty. A little tip: as the individual forms really are quite small - pour in the batter with a measuring cup with a pointed spout - works perfectly!
