Passover Apple Cake

Preheat the oven to 350 degrees F (175 degrees C). To prepare, grease an 8-inch square baking dish with a generous amount of vegetable shortening.

Next, whisk the egg whites in a suitable bowl using an electric mixer until they become stiff and hold their shape, forming sharp peaks that maintain their structure. Set the egg whites aside for now.

In a separate bowl, combine the egg yolks, oil, and orange juice. Using an electric mixer, blend these ingredients together until they achieve a smooth and thick consistency, taking around 5 minutes to accomplish. Gradually incorporate 1 cup of sugar into the mixture, stirring well before adding the matzo cake meal and salt. Mix these ingredients until they are fully incorporated.

Using a rubber spatula or wire whisk, gently fold in about 1/3 of the beaten egg whites into the matzo meal mixture. Continue to run the spatula through the center and around the sides of the bowl, repeating this process until the mixture is fully incorporated.

Add the remaining egg whites to the mixture and fold them in until just combined.

Meanwhile, combine the remaining 3/4 cup of sugar with cinnamon in a small bowl. Mix these ingredients together until they are well combined.

Now, spread half of the batter into the prepared baking dish. Distribute the apples evenly over the batter. Sprinkle the apples with about 2/3 of the sugar-cinnamon mixture.

Spread the remaining batter over the apples. Sprinkle the remaining sugar-cinnamon mixture over the top of the cake.

Finally, bake the cake in the preheated oven until it is golden brown, taking around 45 minutes to accomplish. Remove from the oven and cut into squares while still warm.
