Skin and trim the
chicken breasts and coat lightly with the flour.
Sift the remaining flour and corn-flour (cornstarch)
into a bowl, add enough cold water to make a thick
batter. Beat the egg whites to peaks and fold into
the batter.
Heat the deep
oil. Coat the chicken with batter and deep-fry for
about 6 minutes until cooked through and the batter
crisp and golden, remove and drain well.
Bring the stock
to a boil in a small saucepan and add the lemon
juice, coloring and lemon essence. Season on taste
with salt and pepper.
Mix the
tablespoon of corn-flour (cornstarch) with a little
water, stir into the sauce and boil until thickened.
Slice the chicken, pour on the sauce and serve at
once.
