Heat up enough oil to deep fry the fish, about 3 to 4 cups, depending on what sort of pot or wok you use.
While the oil is heating, make the batter. Mix the flour, starch, baking soda and salt together in a bowl. In another bowl, beat the egg whites into soft peaks. Add about 1/2 cup of ice-cold water (or cold seltzer) into the flour bowl, then fold in the egg whites.
Fry the ginger and garlic until the garlic just starts to brown, about 45 seconds. Use a skimmer or slotted spoon to remove it to a paper towel. Set it aside for now.
When to oil hits about 360F, coat a few pieces of the fish in the batter and deep fry them until golden brown, about 2 minutes. As they are frying, turn your oven to "warm" and set a cooling rack with a baking sheet underneath it for your fish. Move the finished fish to the rack and continue frying the rest.
When all the fish is ready, toss it with the salt and pepper, the reserved ginger and garlic, and the sliced chiles. Serve garnished with the cilantro.
