A chicken, sausage and shrimp gumbo, made with a butter-based roux, the trinity and okra.
Butter Roux Chicken, Sausage and Shrimp Gumbo
A long time ago, I remember hearing an old wives' tale about combining chicken and seafood together in a gumbo, something to the effect of "land and sea, never the two shall meet," a throw back to Kipling I think. Supposedly, you weren't to mix seafood and chicken in a gumbo.
In my growing up, we didn't. There was seafood gumbo and there was chicken gumbo. There was no mixing of the two together in one gumbo.
Seems like it's actually really a thing though!
