OK, I have to admit it, I am biased when it comes to serrano peppers. I think they are the best hot peppers out there! The heat is nice and sharp but goes away quickly which means my face stays sweat free. Trapio Serrano Pepper is a hybrid serrano pepper variety that produces abundant yields of extra large peppers. These peppers average 5-6″ long and are almost most twice as large as standard serrano varieties. They have a moderate heat that is great for slicing into rings for eating raw or cooking.
