Add jalapenos to a small pot and cover with water. Bring to a boil over high heat and cook until jalapenos have softened, about 10 to 15 minutes.
While jalapenos are cooking, add tomatoes, onions, garlic, and cilantro to blender and blend until salsa is smooth.
Once jalapenos have softened, cut off stem and add to blender one at a time and blend. Make sure to taste the salsa after adding each jalapeno. You never know how hot the jalapenos are going to be so you want to make sure to taste the salsa before you add another one.
Once salsa has reached your desired heat, add salt and serve.
