Combine Masa Harina, lard, salt, and activated charcoal in a large bowl and mix well.
Add ¾ of the water and mix. You are looking for the perfect consistency which is soft but not crumbly. Add more water as needed. Cover with a wet towel and let sit while your griddle heats over high heat.
Take a gallon size ziploc bag and cut each side so the bag unfolds.
Place about 3 tablespoons of dough in a ball in the middle of the bottom part of the bag.
Fold the top over and press into a tortilla with a glass pyrex pan.
Place tortilla on hot griddle and cook for 1-2 minutes on each side. Remove and wrap in dry towel.
When ready to make tacos, reheat tortillas with a little oil on the griddle.
