Process the Ingredients - Using a blender or food processor, add the cilantro, parsley, red wine vinegar, garlic, salt, cumin, and crushed red pepper. Mix for 20 seconds to break down the leaves, stopping to scrape the sides of the cup as needed.
Add the Oil - With the machine running on low speed, slowly add the olive oil in a thin steady stream in the lid or feed tube opening. Cover and process on medium-high speed until smooth and slightly thickened, with some small herb pieces, for about 60 to 90 seconds. Season with salt and pepper to taste.
