Begin by preparing the creamy jalapeno ranch sauce. Combine cilantro, pickled jalapenos, their juice, mayonnaise, sour cream, ranch seasoning, garlic powder, salt, and lime juice in a bowl. Whisk until smooth.
Preheat a skillet over high heat for the burgers. Form beef into thin patties and season with salt and pepper. Cook for about 3 minutes on each side until they develop a crust.
Assemble your tacos by placing a burger patty on each tortilla and topping it with street corn mixture and jalapeno ranch sauce.
