Begin by finely mincing the jalapeño, serrano, and red chili peppers. Make sure to remove the seeds and white membranes as they contain most of the heat. Protect your hands by wearing gloves while handling hot peppers.
In a petite mixing bowl, combine the minced peppers with tangy tomato ketchup, creamy mayonnaise, fiery hot sauce, pungent garlic, smoky paprika, tart lime juice, along with a pinch of salt and black pepper. Stir vigorously until all ingredients are uniformly blended.
Sample the sauce and adjust the spiciness to your preference. For an extra kick, add more hot sauce or minced peppers. If you prefer a milder version, mix in additional mayo or ketchup.
Allow the sauce to chill by covering the bowl with plastic wrap and refrigerating it for at least an hour before serving. This will enhance the flavors and create a mouthwatering experience. Serve chilled alongside your favorite dishes, just like it’s done at McDonald’s.
