Peel, core and thinly slice apples. Beat eggs, sugar, salt, cinnamon and milk until blended. Add flour until batter is stiff. Add lemon juice and lemon rind (use a grater to get the lemon rind). Fold the apple slices into the batter. Drop by large spoonfuls into 375 degree canola oil in the deep fryer. Fry until golden brown on both sides. Drain on paper towels and sprinkle powdered sugar on to serve.
