A whipped cream dispenser utilizes pressurized gas, typically nitrous oxide, to transform heavy cream into a frothy, airy texture. Here's a step-by-step breakdown of the process:

1. Filling the Dispenser:The dispenser is filled with heavy cream. The amount you can fill depends on the size of the dispenser, but it's generally around 1/2 to 2/3 full.
2. Inserting the Gas Cartridge:A nitrous oxide canister is inserted into the dispenser. This canister is threaded into place and secured tightly.
3. Pressurizing the Cream:When the canister is inserted, the nitrous oxide gas is released into the cream. This gas creates pressure within the dispenser.
4. Dispensing the Whipped Cream:When you press the lever or button on the dispenser, the pressurized cream is forced out through the nozzle. As the cream exits the dispenser, the pressure causes it to expand and form whipped cream.

The key to the process is the combination of the pressurized gas and the heavy cream. The gas creates bubbles within the cream, while the heavy cream's fat content helps to stabilize the bubbles and maintain the whipped cream's structure.
