Quick reference on how to fry Mandu...
Lightly cover frying pan with oil and fry on medium heat. If it's too high Mandu might burn without properly cooking the inner part. We don't want that!
I usually don't like frying things since oil splatters on my arms...ouch...let's make sure you don't get burned and cover the pan.
Cook both sides and when it gets golden brown, turn it off and enjoy with soy sauce! Yay!
