Preheat oven to 180 degrees C. Butter a large baking tin or casserole dish.
In a bowl, combine water and 1/4 cup apple juice. Break up the matzos into large pieces and soak in the water/juice until just softened. Drain in a colander and set aside.
In a bowl, combine the brown sugar and remaining apple juice until sugar is dissolved. Toss the sliced apples with this mixture and set aside.
In another bowl, beat the eggs then add the salt, cinnamon, sugar, melted butter and apricots. Mix well.
Add the drained matzos and the apples to the egg mixture. Stir lightly and pour into the baking tin. Dot the top with a couple of teaspoons of butter and bake 1 hour. If it starts to brown too quickly, cover with foil.
