First, when I posted that recipe it was actually a link to a scan of the recipe. The moderators actually transcribed the recipe. Thanks!
Here is a link to the original scan
http://scorpiolounge.googlepages.com/crab.bmpHowever, it reminded me that I think there is an error in the original recipe. It lists 1 pound of flour and 1/2 pound of butter. That's not a usual ratio of flour/butter for thickening. So I cut the flour down to 1/2 pound. Sorry, my details are a little sketchy, but I had cut the recipe in half too, so kinda hard to remember all the little details...
Ok, jerk seasoning recommendations:
McCormick makes a Caribbean Jerk Seasoning. Good all around dry blend. Moderate heat. Nice balance of sweet and spice. Should be easy to find. Meijer's carries it around Cincy.
Helen's Tropical Exotics Jerk Seasoning. Good dry spice, little on sweet side. Mild heat.
Busha Browne's Jerk Seasoning. This comes in little jars and is a wet seasoning. Great flavor and it packs some heat! Little goes a long way. I also put just a dab of it in a couple of tablespoons of mayo to use on sandwiches. YUM!
And one to avoid is the Jerk Seasoning put out by The Spice Hunter. Lacks any sweetness, spice blend is poorly balanced.
I would try the McCormick and also look for the Busha. My two favorites.
