I know the best ceviche in the world is from Peru, trust me, my girlfriend is Peruvian and she's introduced me to some amazing and legit ceviche BUT this is my take on the ceviche that I grew up with. Mexican ceviche. It may not be globally regarded as the best ceviche but it holds special place in my heart. To make this even more legit to the classic Mexican style, I highly recommend adding a bit of ketchup or Clamato. Don't think about it, just try it.
