re: Shrimp Gumbo - how to fix chewy shrimp?

I really detest overcooked shrimp in gumbo that has been simmered into smithereens. That's another reason I love Downtown Don's shrimp gumbo. They add the shrimp when you order it. They are just cooked, plump, fresh and pristine in color. Same with their seafood gumbo. They make the base and add the seafood to serve. That's how I do it at home.
