Heat the coconut oil in a frying pan over medium heat.
Peel the plantain(s).
Depending on size, cut the plantain into 3 or 4 chunks.
Slice the chunks lengthwise.
Place the chunks into the frying pan, and fry 2-3 minutes each side. You do not want them fully cooked.
Remove them from the pan and smash with either of the methods below.
Place the smashed plantains back into the frying pan, and fry again on each side until they're a light golden brown.
Smashing Methods
1- Take the once fried plantain and place between the boards of a totonera. Squeeze firmly.
2-Place the parchment off center on one plate, and the once fried tostone on top. Then fold over the parchment paper and place the other plate on top. Press down firmly and evenly and you'll get the same result!
Notes
To get an extra large tostone like ones used for a jibarito (a classic Puerto Rican sandwich), slice the chunks at an angle so they lave more length to them.
You can buy a totonera on amazon and easily smash the plantains! I still like using parchment paper to keep it clean.
