I had already bought the 20cm round classic mold (see my other reviews) and I was totally satisfied to bake my bread. But for some special bread is a little big. I wanted to buy a smaller model. When I found that only 18 cm round mold is more expensive than this kit, I did not hesitate. And as always with this brand, I'm not disappointed. The round mold is the same quality as the one I had. When the square mold received extra I used it to make small bricks and brioche bread with grape called ceramics in Belgium. It perfectly demold and cooking is perfect. Furthermore it does not deform as the silicone mold I used before. The ability of the two molds is identical. We can prepare a mixture and pour half into each mold to have a different shape. As regards the recipe book, ada! There are just a cake recipe in French on the packaging! Contrary to what is called, I do not grease the molds before use and for maintenance, a swipe is enough. Despite this, I pass them in the dishwasher without problem. If you are looking for small mussels, look no further, you will not find better. Tip: Although open and let them dry in the open air before storing. I spent time writing this review to you.
