Chile Serrano is a small and slender chili pepper commonly used in Mexican cuisine to add heat and flavor to dishes like Tacos al Carbon. It has a medium level of spiciness, slightly milder than the jalapeno pepper. To use Chile Serrano as a topping for Tacos al Carbon, finely chop the pepper and sprinkle it over the assembled tacos. The spicy kick of the Chile Serrano adds a fiery and bold flavor to the tacos, balancing out the smoky and tangy flavors of the grilled meat. Adjust the amount of Chile Serrano according to your spice preference. Enjoy the combination of the grilled meat, fresh toppings, and chopped Chile Serrano for a tantalizing and spicy meal!
