Step 1: Prepare the Crab: Gently flake the crab meat, removing any shell fragments. Be careful not to shred the crab too finely; larger pieces retain more flavor and texture.
Step 2: Combine Wet Ingredients: In a medium bowl, whisk together the mayonnaise, lemon juice, Dijon mustard, celery seed, salt, and pepper. Ensure the mixture is smooth and well combined.
Step 3: Incorporate Vegetables: Add the diced celery and red onion to the dressing. Stir to evenly distribute the vegetables throughout the creamy base.
Step 4: Fold in Crab Meat: Gently fold the crab meat into the dressing mixture. Avoid over-mixing, as this can break down the delicate crab meat. Aim for a homogenous distribution of ingredients.
Step 5: Chill and Serve: Cover the bowl with plastic wrap and refrigerate for at least 30 minutes to allow the flavors to meld. This chilling period enhances the overall taste of the salad. Serve chilled on crackers, lettuce cups, or in sandwiches. Garnish with fresh parsley, if desired.
For a tangier salad, increase the amount of lemon juice. If imitation crab is used, consider adding a pinch of sugar to enhance its sweetness. Adjust seasonings to taste. Serve immediately after chilling for the best flavor and texture.
