Sous Vide Ball for cooking

Preventing Evaporation.

Insulation helps prevent evaporation from the pot. This is especially important for longer cooking periods or when cooking at higher temperatures.

Increasing Efficiency.

Besides evaporation control, having a lid of sorts helps with energy use and efficiency. The more heat that stays in the vessel, the less works to maintain temperature.

Maximizing Tank Capacity. 

Proper insulation also allows you to cook with containers beyond the recommended maximum tank capacity.

Flexibility.

Sous vide balls can be dropped into any container to insulate it, no matter what size and shape as long as there are enough to cover the surface of the water.

Cost.

A quick search shows most ping pong ball packages (you need 75-100) are half the cost of a standard lit.

Hassle-free. 

Another bonus is the ability to add food, adjust the placement of food, or remove food without hassling with an additional lid. Just reach right in with some tongs, or grab the edge of the bag.

Easy Clean-up.

When you’re done, just drain the water through a strainer to catch the sous vide balls, then store them in your container to reduce your kitchen clutter.
