My son is a big sousvide cooker. He loves it. He loves to cook and bake and cook in general.I use the vac sealer primarily for meat that goes in the freezer. No freezer burn and it stores longer this way. But I also use the sous vide cooking method for a lot of items in the summer so it’s dual purpose. Plus, I can store prepared meals in them and rewarm right in the bag. Less mess and water use. I just pour boiling water over the bags and let them sit in a bowl covered.
