When I was a kid (1940's) my mother used to buy "Devonsheer Wafers". These were sharp cheddar process cheese filling in a sandwich of miniature waffles -- about the size of a Ritz cracker. I was crazy for these, but eventually they disappeared from stores.
After many years, I found them again, now called Old London Waffle Snacks, sold at a Safeway market in Manhattan Beach, CA. Then they disappeared again.
Last year, I discovered that I could buy them from Ralphs Online, and I consumed a couple of cases of them. I just tried again, though, and found that Ralphs no longer carries them (even online). Amazon shows them, but lists them as Out of Stock.
I found a website for Old London, and asked them about them; they told me that they had sold the brand. They suggested that Wise Waffie Snacks were the same recipe, so I tried that: again, no longer available. Amazon says that these are currently not available, and they don't know if they will be again.
These things are addictive. The cheese is tangy, like Kakauna Club Extra Sharp (also getting hard to find), and the waffle crackers have a wonderful crunch to them. I crave them passionately, but fear that they are another of my favorite foods that are going out of existence.
Sorry to whine at you. Anybody know anything I've missed; any comparable products that are still available?
