We ordered a dip like this at a restaurant recently and I decided to try and re-create it. Thanks to the "chipotle" suggestion from my bud Riff I believe this is exact. It may sound awkward with crawfish but I assure you it is wonderful and ever so easy to make.
Ok, not sure where the "Texas" part comes from but this is an excellent easy recipe and a nice change of taste. Credit for the original recipe goes to Mark Picker of Central Market with a few changes from me - i.e. extra garlic of course! ;)
