Balancing work, family, school, sports, and so on while also paying attention to a healthy diet can sometimes be quite challenging. With the Cook&Heat series from Pyrex, this is no longer an issue. The borosilicate glass containers allow you to prepare your meals, cook them in the oven, keep them cool, and later reheat them in the microwave according to your preferences and needs. Quality and speed: Thanks to the patented vented lid, specifically designed for steam release, both are finally achievable.
