Sauerkraut

When I got home from my trip my sauerkraut was ruined. As per this post I was making some homemade sauerkraut, which I have made before. But this batch got mold on the top (the cabbage came above the water.) I was thinking of just scrapping off the mold, but I didn't want to get sick. Last time I made it I checked daily to keep the cabbage underwater, but not checking it while I was away ruined it. At least my cabbage was less than a dollar, but I still hate to waste.
