Once the bottoms are crispy, drop the heat by a bit, then pour approx. ¼ - ½ cup of water (enough to cover the base of the pan) into the pan and immediately coverwith a lid, be careful it’s going to splatter so do it quickly. Let it steam for 8-10 minutes, uncover and let the water evaporate off. Fry for an extra 5 minutes to crisp up the bottoms again.
