We love this with lobster tails and snow crab legs, but it’s just as good with wings, boiled shrimp, or any fresh seafood. It’s also great for dunking corn on the cob or boiled red potatoes for extra flavor.

Mel’s kitchen notes

For the best flavor I use a homemade Cajun or Creole seasoning. If you don’t have one, a store-bought brand like Tony Chachere’s works well.
