If there’s a magic formula for making a truly craveable snack, we postulate that it would have to go something like (sweet X salty)^(crunchy). It would follow, then, that optimal craveability would be theoretically achieved by optimal sweetness, optimal saltiness, and optimal crunchiness.

Could such an optimal snack exist? Is such mathematical snack perfection possible? We have three magic words for you: Butter. Toffee. Pretzels.

Combining the sweetness of delicious, sugary toffee with the saltiness of oh-so-snackable pretzels (and elevating them by to the power of their combined crunchiness), Trader Joe’s Butter Toffee Pretzels are a snack so utterly craveable, so perfectly designed to make you say “why, sure, I could go for another handful,” that they could only be the product of some kind of magic ratio of salty-sweet synergy.
