Zwilling's Fresh & Save is a revolutionary way to keep your food fresh up to five times longer. Like the wine bottle vacuum pump you are probably familiar with, air is pumped out of the container using a handheld pump. In this case, an electric one that makes it as easy and convenient as possible. Included in the starter kit are four reusable bags in two sizes (S and M) and two glass boxes with lids (M and L), all of which have a valve where you suck the air out of the container after filling. Not only do you reduce your waste by keeping your food fresh for much longer, you also reduce your consumption of plastic bags, vacuum bags and plastic film. The glass boxes are oven (without a lid up to 180°C), fridge, freezer, dishwasher and microwave safe so you can, for example, cook a gratin directly in the box, let it cool, deflate and freeze without making a mess. Of course, they are also stackable both with and without a lid.The bags can withstand fridge, freezer, microwave and heat up to 100 ° C, which means that you can both freeze and cook food in your sous vide in these bags, and also wash them for reuse. The pump charges easily with the included USB cable. Then place it on the valve and press and the air will be sucked out. The set includes a pump, two glass jars, four bags and a charging cable. More accessories, such as blender jug lids or wine corks, can be purchased separately.
