I have never met a dipping sauce that I don't like, lol. My favorite is a simple Sriracha Mayo. I add a 1/2 cup of mayo, 1 tablespoon ketchup, and as much sriracha as you like, starting the a teaspoon and keeping adding until it meets your spice level! I also like this Lime Aioli - Molho de Limão e Alho. You can also use your favorite marinara sauce or Dijon mustard.
