It's Cuki innovation, it is what makes the difference in cooking. We're talking about the new no-stick aluminium containers, suitable for all food, even the most acid (like tomatoes and lemons) and salty ones. Their special no-stick inside-surface avoids the food from sticking to the borders, making every operation extremely easy and practical. Its copper look-like outside-covering makes them recognizable from other products; the new trays are ideal for lighter fat meals and oil free cooking. They will turn out to be perfect at any temperature: fitting the oven as the freezer.
