Preheat oven to 375F.
Mix all ingredients except apples by hand in a bowl, breaking up the bread and preserves as you go.
Gently fold in apples so as not to extract more moisture.
Pour the batter into a greased 9x13 inch pan, a greased 10-inch round pan or a dozen greased muffin molds.
Bake for about 1 hour (about 40 minutes for muffin molds), or a little longer, until the pudding looks nice and puffy, and the center is firm.
Serve warm or at room temperature, alone or with caramel sauce, and a scoop of sorbet or vanilla ice-cream.
