The process involves using a pressurized canister, often manufactured by iSi, to create a light, airy dessert topping. This method typically combines heavy cream with a sweetener and, optionally, flavorings within the canister. The contents are then dispensed via a nozzle, resulting in a freshly made, voluminous cloud of cream. For example, one might charge an iSi canister filled with cream, sugar, and vanilla extract, then dispense it atop a slice of pie.
Employing this technique provides several advantages, including control over ingredients, freshness, and texture. Unlike pre-made alternatives that may contain stabilizers and preservatives, homemade preparations enable ingredient customization and often produce a superior flavor profile. The pressurized dispensing also results in a lighter texture compared to traditional whipping methods. Historically, similar techniques have been used in professional kitchens to achieve consistent results and efficient service, now accessible for home use.
