In a large bowl, combine the first eight ingredients. Stir in bread cubes and raisins. Transfer to a greased 13x9-in. baking dish. Bake, uncovered, at 350° for 45-55 minutes or until a knife inserted in the center comes out clean.
For sauce, combine the sugar, cornstarch, salt and water in a large saucepan until smooth. Bring to a boil over medium heat, stirring constantly. Remove from the heat.
Stir a small amount of hot filling into egg yolks; return all to the pan, stirring constantly. Bring to a gentle boil; cook and stir for 2 minutes.
Remove from the heat; gently stir in lemon juice and butter. Serve with bread pudding. Refrigerate leftovers.
