Begin by adding roughly around ½ cup of oil to your frying pan (oil should be an inch deep). Start heating the frying pan over medium heat.
You need to flatten the golden plantains and a bamboo tostonera is perfect for this. If you do not have one, using a coffee cup or a similar flat object like a plate to smash them. Then you will fry them once more while flattening for another 2-3 minutes per side or until crispy golden brown
Remove them from the frying pan and place them onto a wire rack or a plate with paper towels to soak excess oil. After the tostones have cooled down a bit, sprinkle salt over them for taste.
