I am a hot head and cook with all types of chili peppers but one of my favorites is Sriracha Chili Sauce. I make my own version of sauce that is not quite a sweet but if you add sugar, you first taste the sweet and then the heat.
If you watch Amazon videos, do a search for Sriracha. If you have an Amazon Prime account the video is free. I think you will find the video both entertaining as well as educational.
My red Jalapeno peppers are fermented with Lacto bacteria, salt and sugar. Rinsed and then pickled with salt and a 50% mix of 5% vinegar and water.
