Ideal for sous vide cooking liquids or liquid-rich foods including marinades, sauces, stews, soups, custards, risotto, infused alcohol and more! SousVide Supreme zip pouches/bags, certified as food-safe and stable at cooking temperatures, are specially designed to simplify the process of sealing dishes containing more than a tablespoon of liquid. With a few simple steps, air can be evacuated without the aid of a chamber vacuum sealer, making it easier to submerge pouches containing food and liquid. Includes 25 pouches/bags per box. Please note: these bags do NOT contain a valve and will not work with the Zip Sealer.
