Break down mangoes - Peel the mangoes, slice the plump cheeks away from the pit, then (using a very sharp paring knife) cut the remaining fruit from the pit. Cut into small, even strips.

Combine with the tajín - Sprinkle tajín generously over mangoes, keeping in mind it's spicy! Use your hands to mix it in fairly evenly. You'll be using your hands to place them on dehydrator trays, so go ahead and get them sticky!

Place mangoes on dehydrator trays - Place the mango slices into the food dehydrator in a single layers. It is important to not crowd the fruit on the trays!

Cook the tajín mangoes - Cover and cook at 135° for 8-10 hours. Cooking time varies according to thickness of mangoes, humidity level, and temperature of your appliance (mine runs at 135°). I start checking at around 8 hours. You're looking for pliable fruit that is not overcooked. You don't want chips!
