Swampfire seafood boil

I’ve never tried it and before I do I’m hoping to get a list of ingredients. I currently use a “cajun” mix of cayenne, salt, garlic powder, onion powder, black pepper and paprika. From googling it kind of looks like they add some lemon zest and??? Anyone use it and have a guess on ingredients?

Allspice and a variety of veggies too.

Here’s an Alton video from Good Eats that lists the spices in basic boil recipe.
