I just purchased a bag of Ruffles Thick Cut Cheddar Baked Potato chips and immediately was struck by how much they remind me of O'Grady's Au Gratin chips. Although it has been many years since they disappeared, this Ruffles flavor brought back what is seared into my taste-memory for O'Grady's Au Gratin potato chips.
I wanted to get opinions from other 'hounders who remember O'Grady's and have tried this variety of Ruffles. If anything, I remember that O'Grady's may have been even thicker than the Ruffles but that doesn't detract from the taste.
I remember being really mystified as to why this product just disappeared from the shelves when my friends and I could not get our parents to buy them fast enough. Maybe, they are back.
