I made a pickle by placing cucumber in a solution of water+vinegar+salt, and left it for 3 weeks. When I opened it, it was covered with white mold all over the solution.
Can I skim the mold from the solution and use the pickle? Does it go inside the solution and cucumbers?
What is the reason for the formation of mold, and how can I avoid it in the future?
Can it be
kahm yeast? If yes, how can I tell it from mold?
