Key Lime Mustard Sauce is a bright, tangy condiment that pairs beautifully with boiled shrimp, crab, or flaky fish. It’s simple to make and perfect for summer gatherings or a tropical-themed meal at home.
Serve this sauce with easy summer seafood recipes like a crab boil or fried shrimp sliders. I like to offer a couple of dipping options when I serve seafood so guests can choose a flavor that complements the natural sweetness of the seafood.
Key West Shrimp Recipes
If you’re craving Key West flavors but can’t make the trip, bring the island to your backyard. A small tropical party with Key West-style shrimp and bright citrus sauces creates the same relaxed vibe without the travel.
Key Lime Mustard Sauce captures that tropical brightness — the tartness of Key lime balanced with mustard and buttery richness — making it ideal for dipping boiled shrimp or serving with crab or fish.
Florida Pink Shrimp
My favorite seafood is Florida Gulf pink shrimp. Their natural sweetness and tender texture are hard to beat. I often keep seasoning light when cooking them to let that fresh shrimp flavor shine, then serve a bold dipping sauce on the side.
Lightly boiled or steamed pink shrimp are perfect with a flavorful sauce like this Key Lime Mustard Sauce — it complements the shrimp without overpowering it.
Shrimp Dipping Sauce
This Key Lime Mustard Sauce recipe has been in my binder for years. The recipe originally came from the makers of Nellie & Joe’s Key West Lime Juice and was featured in Gardening Magazine in 1999. It continues to be a favorite for seafood parties and casual meals alike.
How To Make Key Lime Mustard Sauce
Key Lime Mustard Sauce is straightforward and quick. Combine the ingredients in a saucepan and simmer until slightly thickened. The result is a tangy, buttery mustard sauce that works beautifully with shrimp, crab, or fish.
Key Lime Dipping Sauce
Minced green onion and garlic form the aromatic base. Place the butter in a large saucepan or skillet, then add Worcestershire sauce, Dijon mustard, cooking sherry, and Key lime juice. Stir in the minced green onion and garlic and bring the mixture to a gentle simmer over medium heat.
Whisk as the butter melts and continue to simmer, whisking occasionally, for about 10 minutes or until the mixture is slightly thickened. Remove from the heat and transfer to a serving bowl or spoon into individual appetizer cups.
For individual shrimp appetizers, add three peeled, cooked large shrimp to each mini glass or cup and ladle the sauce alongside. The sauce also pairs well spooned over crab or a simple grilled or steamed fish.
Shrimp Dipping Sauce recipes
If you like variety, I often serve this Key Lime Mustard Sauce alongside other dipping options. A spicy garlic sauce is my go-to for boiled shrimp, and I sometimes offer a selection of four sauces — a creamy tiger sauce, homemade tartar, cocktail sauce, and a sweet mango-peach chili sauce — so guests can mix and match.
Key Lime Recipes
Finish your tropical meal with a slice of homemade Key lime pie or a frozen mango-Key lime pie for a refreshing dessert that complements the savory seafood flavors.
