3D Doritos

Frito-Lay took the flat Dorito, inflated it into a hollow triangle, and created the most architecturally ambitious snack of 1998. The puffed shape held more flavor dust per surface area than the original. You could stack them. You could crush them and hear the satisfying hollow crunch. Discontinued in the US around 2004, they were briefly revived in 2021 as "3D Crunch" — but fans insist the texture was wrong. The original 3D Doritos Jalapeno Cheddar remains the holy grail of discontinued snacks.
