Combine the flour, baking soda, sugar, and seasoning; add the egg yolk and enough milk to make a thick batter. Beat the egg white until stiff and fold in.
In a deep fat fryer, heat the oil to 350 degrees. Dip the rabbit pieces into the batter, letting the excess drip back into the bowl. Then carefully place the pieces into the oil one at a time. Do this slowly to maintain the cooking temperature of the oil.
Cook about 10 minutes, or until the pieces turn rich golden brown on the outside, and the juices run clear. Serve with mashed potatoes and peas.
