Peel and split the bananas lengthwise. Cut each piece in half and dip in lemon juice. To make batter, beat the egg yolks until thick and light. Add flour and salt. Beat egg whites until stiff, not dry, and fold into yolks. Drop the drained bananas pieces into the batter, one at a time. Pick up with slotted spoon and slide gently into hot oil in heavy skillet (oil about 1 inch deep). Cook over medium heat, turning almost immediately. Cook until browned on both sides. Drain on paper toweling.
Note:If plantains (fat, red-skinned cooking bananas)are not available, use large, green-tipped bananas. DO NOT use overripe bananas.
For frying, use part olive oil, part Canola oil.
