I call this fish “lightly puffed” because of the way I make the egg batter. First, I beat the egg whites until they are very foamy, and then I gently whisk the egg yolks into the whites before dipping the floured fish into the egg. This results in a light, puffed coating on the cooked fish. Throughout the Basque Country, you will find all types of filleted fish pan-fried this way. The fish is great with a green salad and Basque Fries.
