How to Make It
In a blender or food processor, pulse corn and green onions until chopped but not smooth. Transfer to a large bowl and stir in 2 tbsp. oil and the egg yolks.
In another large bowl, combine flour, cornmeal, salt, and pepper. Add to corn mixture and mix thoroughly but gently.
In a large clean bowl, whisk or beat egg whites until soft peaks form. Fold into corn mixture.
In a large frying pan, heat 1 tbsp. oil over medium-high heat. Working in batches, drop large spoonfuls of the corn mixture into pan (do not spread or flatten). Cook until edges begin to set and undersides are browned, about 2 minutes. Flip and cook until cakes are browned and cooked through. Cook remaining batter the same way, adding oil as necessary. Serve hot.
