Warm 1 tbsp of tallow or butter in a cast iron skillet over medium heat until the pan is hot.
Add 1 pint of shishito peppers to the skillet, letting them cook for about 10-12 minutes. Turn them halfway through the cooking time until they are browned and blistered.
In a small bowl, combine 1/4 cup mayonnaise, 1 tsp ketchup, 1 tsp hot sauce, 1 tsp Worcestershire sauce, and salt and pepper to taste. Mix well until smooth.
Once cooked, transfer the blistered peppers to a plate lined with a paper towel and sprinkle them with sea salt.
Enjoy the hot blistered shishito peppers with the homemade comeback sauce for dipping.
