Reddi-wip is the brand of nitrogen-or-isobutane-propelled, sweetened whipped cream produced by ConAgra Foods. It is sold in the following varieties: Original, Extra-Creamy, Light, Fat-Free, Non-Dairy, and Chocolate. The Original and Extra-Creamy come in 7oz. and 14oz. cans. All other varieties, except Chocolate, come in 7oz. cans only; with Chocolate available in 6.5oz. cans only. (The Reddi-Wip site even promotes consuming the Chocolate variety, especially, on its own, presumably - as is popular with many people - dispensing it straight from the can into one's mouth.) Despite being available in an aerosol can, it should be treated as regular cream: sealed and refrigerated when not being used. Nitrous oxide, the propellant used in Reddi-wip (and approved by the Food and Drug Administration (FDA)), is the same gas that is used as both a weak anaesthetic (primarily by dentists) and a performance enhancing oxidiser in motorsports.
