You are right, I just googled and could find nothing similar. If I remember correctly, this was salt, dill, garlic, and cream of tartar in a powder form, not what I see online. I bought it on close out for 10 cents in a vacuum bag and put it in an empty spice shaker so I can not say exactly what it is.
In the crust, notability when reheated today, are the garlic and dill tones. I normally give the dogs my pizza bones (crust), but I ate them all on this batch.
