Mix the masa harina together with the salt.
Stir in the hot water.
Keep stirring until a dough forms. Form it into a ball and let rest for 20 minutes.
After resting divide dough into 8 equal parts and form into balls. Let rest.
Press each ball with your tortilla press (I like to put parchment paper on it to help it not stick)
Grill on med-high heat for 30-45 seconds.
