Start by assembling all the necessary ingredients. This can help streamline your cooking process. Have your shrimp, mustards, spices, and fresh herbs ready for action.

In a large bowl, combine the Creole mustard, yellow mustard, ketchup, and distilled white vinegar. Stir them together until they are fully mixed. This forms the flavorful base of your remoulade.

Now, it’s time to spice things up! Add in the smoked paprika, cayenne pepper, and sea salt. These will give your sauce a lovely warmth. Stir the mixture again until all the spices are well integrated.

Next, finely chop your green onions and celery. Add these to the bowl. Now, press or chop the garlic cloves and squeeze in the lemon juice. This combination will introduce freshness and a bit of crunch.

Fold in the boiled shrimp gently. Make sure they are evenly coated with your mixture. This is where the magic happens; the shrimp should absorb all those flavors, so each bite is a delight.

Taste your sauce. Does it need a bit more salt or spice? Adjust according to your preference. Finally, mix in the Worcestershire sauce and fresh parsley for that extra layer of flavor. Give it one last stir – you’re done!
