– Place chopped peppers and ½ cup of water in your blender. Process for a few seconds until you get a semi-coarse texture. If you over blend it and comes out with a fine texture, it’s fine. No problem with that.
– Heat oil in a frying pan. Once the oil is hot, add the chopped onion, fry for about one minute, just enough time for it to get transparent.
– Now, pour the Serrano peppers mixture. Once it starts boiling, reduces heat and covers the frying pan. If the liquid reduces while cooking adds a few tablespoons of water. It will take about 8 minutes to cook. You will know the salsa is ready when the peppers have changed from a bright green color into a light pale green color, and the oil will float on the surface. Season with salt and enjoy.
