Know before you buy
By creating a floating layer on the surface of your water bath, the balls significantly reduce heat loss and evaporation. This helps your immersion circulator maintain a more stable temperature and prevents water levels from dropping during long cooks.
Yes, the balls are designed to be versatile and will adapt to the shape of any open cooking bath, whether you are using a dedicated sous vide container or a standard stockpot.
Yes, the balls are made from durable polypropylene and are heat-resistant up to 230°F (110°C), which covers the entire range of standard sous vide cooking temperatures.
The included mesh bag is designed for both storage and use. You can leave the balls in the bag while cooking for easy removal, or use it to rinse and air-dry them before storing them away.
You should use enough balls to create a single, complete layer covering the surface of your water bath. If you are using a smaller container, you may not need the entire pack, but having 100 ensures you have enough coverage for larger vessels.
