Place the egg yolks, oil, and orange juice into a mixing bowl; beat with an electric mixer until creamy and thick, about 5 minutes. Stir in 1 cup of sugar, mixing well, then lightly stir in the matzo cake meal and salt. Use a rubber spatula or wire whisk to fold about 1/3 of the beaten egg whites into the matzo meal mixture. Gently run the spatula through the center of the mixture, then around the sides of the bowl, repeating until fully incorporated. Add the remaining egg whites, folding until just incorporated.
