Missing : chart about temperature and time for pasteurization
It wa very difficult to listen to automatic English speech. In some places, the translation is not correct or repeated several times. I had to stop and turn on the subtitles. The pasteurization process is described very abruptly. It remains not clear to put the jar in a pot with hot water or in cold water and heat it up to 70-95C. The chart for pasteurization time is missing .
