This 5-ingredient seafood mustard sauce is my go-to for when I want to elevate any seafood and make it taste restaurant-worthy. It's spicy and bold, and it's the perfect creamy dip for anything from crab legs and shrimp to oysters and lobster.
Grate the shallots with a microplane or cheese grater.
Measure all the ingredients and place them in a small mixing bowl.
Stir well to combine. Then cover and chill until ready to serve.
Notes
Add extra horseradish for a spicier sauce. This dipping sauce is also wonderful on oysters and clams, grilled pork chops, or as a sandwich spread! This mustard should be kept in the fridge when not being served. Some mustards can stay at room temperature; however, the horseradish in this dish needs to be refrigerated. Place it in an airtight container or jar and refrigerate for up to 3 weeks.
