add the batter into the pan, press around to create a round 1cm thick pancake. fry for about two minutes on medium heat. you can tell its ready when the pancake moves when you shake the pan.
EDIT: if you want to add seafood, meat this is where you do it. lay pieces of meat or seafood on top. it will cook when you flip it. i recommond thinly sliced pork or fresh squid ring. squid is really good. but i usually just have it plain. google for more ideas.
