Me first: in the early 80s, I remember the Vons supermarket chain had their own brand of sour cream dip for potato chips, one flavor that people I know loved was fresh pismo clam, it still had chunks of clam meat in there. One day it got yanked from the shelves and I’ve never seen it again.
More recently, about a decade ago, Trader Joe’s carried cheddar-and-horseradish potato chips, then one day they were gone.
I would love… LOVE… to dip those horseradish chips into that clam dip… sigh.
In the 1980s, Frito Lay test marketed a new extruded Cheeto-like product that was filled with an easy cheese filling. There was even a pbs documentary about it centered around how new snacks are made.
I wish I could remember the name of the snack and/or find the documentary online. They were yummy but they didn’t last long. I think there were like three different flavors and they were cut at an angle.
