Combine all of the marinade ingredients in a blender. Set aside.
Place the chicken breasts between sheets of plastic wrap and gently pound to ¾” thick with a meat mallet. Season with salt and pepper then place in a container and add one and a half cup of Mango Coconut Marinade. Marinate in refrigerator for four hours up to overnight.
While the chicken is marinating make the tortillas.
Combine the masa, beer and salt in a bowl and mix with your hands until the dough comes together. The dough should be soft and not too sticky. If too wet add a little more masa, up to ¼ c, if too dry add a little more water or beer. Wrap in plastic wrap and chill in refrigerator for 30 min. Form into 16 balls, about golf ball sized. Preheat a cast iron griddle or skillet, but keep dry. Do not add oil or butter. Working with one dough ball at a time, place plastic wrap over the top and bottom of the tortilla press, place one dough ball in the middle and gently press down. Carefully transfer the tortilla to the preheated cast iron pan, peeling away the plastic wrap just as you place on the surface of the pan/griddle. Cook for 1 minute a side, carefully flipping after one minute. Keep warm in a towel as you make and cook the rest of the tortillas .
Preheat grill to 350 Deg F. Grill the chicken, about 7-8 minutes a side, turning once as you grill and basting once with more marinade towards the end of grilling. Remove from grill and let the chicken rest 5 minutes. Slice into ½ inch thick strips and add another ½ cup or so of marinade. Keep warm until ready to serve.
To assemble the tacos:
Place a few strips of chicken on the middle of a tortilla, add a few avocado slices, a few sprigs of chopped cliantro and top with a little more Mango Coconut marinade and hot sauce, such as Cholula or Tabasco, if desired, and a squeeze of lime. Repeat with remaining tortillas and chicken. Serve tacos and rice immediately. Enjoy with a cold Kona Brew Co. Fire Rock Pale Ale.
Notes
You can make the tortillas while the chicken is marinating if you make this all in one day. The chicken is best when marinated longer, up to 12 hours. I often marinate the chicken overnight for maximum flavor.
