Take a non stick frying pan and put it on the fire. When hot add ¼ tsp of butter and a ladle of batter by swirling the pan so the batter coats the base of the pan. You don’t want to make the coating too thin. About 2 mm – 0.08 inches thick will work nicely. When the surface of the crespella dries up, it is time to flip it over. Do so by using a plastic spatula to loosen its sides first and then flip it over. Cook it for a minute more, then remove it from the pan and keep it aside. Repeat this till your batter is over.
