I use Tony’s on everything...potatoes, eggs, casseroles...etc....its fantastic.....
It's mainly just salt and cayenne pepper but in a convenient package and in the right ratio for use on just about anything.
It's great for "layering" crawfish in a cooler prior to serving and in gumbo, use on grilled or roasting chicken, ribs among a myriad of uses.
LOL, we're starting to sound like a commercial for Tony's. There are many custom blends that are better but hard to find outside their local marketing areas.
