@farmerman,
I don't put applesauce in until the kraut is almost finished. Even then, I only use it if the juice is too tart.....I think the pork mellows out the kraut, to me the pork doesn't taste like kraut....its far from the fermented stuff you would use on a Reuben or hot dog. (It has become Julie Mae Gray's sublime sauerkraut) The ribs should just fall off the bone and turn into chunks.....but I love it, its not at all like bbq'd ribs.
Plus, I wouldn't sauté the onions before putting them in a crockpot, if you want sautéed onions, serve them separately. They really should go in raw and simmer with the apples and kraut.
But if you insist on sautéd onions in the pot, just promise me you won't tell anyone who gave you the recipe.
