Reversing an earlier decision, Britain’s Lord Justice Robin Jacob has ruled that Pringles are, indeed, potato chips. The decision means Pringles parent Procter & Gamble will be stuck paying $160 million in back taxes. P&G had insisted that the chips lack enough “potatoness” to qualify as a potato-based product (and be taxed as such), but the Judge disagreed, leaving it to philosophers and nutritionists to determine what exactly qualifies as the “essence of potato.” We kind of feel for P&G on this one. We love that crunch, and the way they stack so neatly in the can, but if we want real potatoes, a Pringle isn’t likely to be our first choice.
