Cast iron a must. Batch cooking absolutely . Cooking 3# of chicken. I have an 8 inch cast iron skillet and a 10 inch carbon steel Tried using a carbon steel to cook 2 batches at a time. The cast iron cooked more quickly and developed better color.
They are delicious. Rotating and switching the pans is critical. My sailboat stamp did not photograph well. Recommend a stamp with more distinct pattern
