I had them last week. They have some nice heat to them. I hate the Blazin' sauce, it has heat but tastes like ass, so I usually throw those on the ground. I think the GP sauce is hotter than blazin but better flavor for a commercial sauce.
I'm in columbus, ohio, home to their first restaurant on the Ohio State campus but I think they're rolling these out nationwide so everyone should be getting them soon.
The Marzetti Company based here in Columbus makes all their sauces for them. I'm not sure how many people have the Marzetti brand available to them, except here in the Midwest, but they make some good salad dressings and dips as well.
