How to Make Big Boy's Tartar Sauce Clone Copycat

  1. In a medium bowl, combine 1 cup mayonnaise, 1/4 cup sweet pickle relish, 2 tablespoons lemon juice, 1 tablespoon capers (finely chopped), 1 tablespoon Dijon mustard, 1 teaspoon onion powder, 1/2 teaspoon garlic powder, 1/4 teaspoon black pepper, and 1/4 teaspoon salt.
  2. Stir well to ensure all ingredients are thoroughly combined.
  3. Cover the bowl and refrigerate for at least 4 hours, or preferably overnight, to allow the flavors to meld and deepen. The longer it sits, the better it tastes!
  4. While the sauce chills, prepare your Slim Jims and sandwich buns.
  5. Grill your Slim Jims to your desired level of crispiness. A George Foreman grill works great for this, or you can pan-fry them.
  6. Toast your buns lightly on the grill or in a toaster oven for a warm, slightly crispy texture.
  7. Spread a generous amount of the Big Boy Tartar Sauce on both halves of each bun.
  8. Add your grilled Slim Jims to the bottom bun.
  9. Top with the other bun half and serve immediately. Enjoy!
