Remove the membrane from the pollock roe and separate the eggs.
Beat the eggs, then mix in the pollock roe and chopped scallion.
Heat a pan over medium-low heat and add cooking oil.
Pour a small amount of egg mixture into the pan and spread it thinly.
When it's about halfway cooked, start rolling it up.
Pour the remaining egg mixture in two more additions, rolling it up each time.
Cook until golden brown and slice into bite-sized pieces.
