Fresno peppers are bright red, jalapeno-shaped peppers with a medium-hot flavor. Most grocery stores carry them, so it shouldn't be hard to find a handful in your own town.
To turn these peppers into a tongue-tingling hot sauce, place them on a hot grill pan with a bit of olive oil and cook until softed and slightly charred.
Make sure you stir the peppers from side to side, to evenly cook them and bring out the flavor from the entire pepper.
Toss the cooked peppers into a blender with vinegar, garlic, and salt. Blend until pureed.
Transfer your hot sauce into an airtight container and it'll keep in the fridge until you're ready to spice up your eggs, tacos, and everything in between!
