Preheat oven to 350°F and grease a nine-inch round or square cake pan.

Break matzohs into one-inch pieces and soak in milk until soft, about five minutes. Drain well and place in bowl. Whisk together eggs, sugar, butter, cinnamon, and salt until well blended. Combine with matzohs and stir in apples, walnuts, and raisins. Pour into baking pan and dot with butter. Bake until golden brown, about 40 minutes. Let cool and cut into wedges or squares.
