With the iSi Gourmet Whip and the Rapid Infusion technique, liquids can be infused with aromas. What was once a question of days or even weeks can be reduced to a few minutes with Rapid Infusion. The Rapid Infusion process using the iSi system was first discovered by the US mixologist Dave Arnold.
How does Rapid Infusion work ?
N2O flows out of the iSi cream charger into the iSi Whipper, forcing the liquid and the N2O to organically combine together under high pressure with the flavoring substance. When the pressure in the Whipper is released, the N2O forms bubbles and takes on the flavors of the ingredient. This means the aroma has been transferred into the liquid.
