2. Only use the lids that were originally on the jar. Mark the lid and jar with a waterproof pen so that you can see this when the label is removed from the jar.
3. Not all jars are suitable for preserving; jars with cardboard seals, such as nut nougat cream, can be disposed of. Inspect the rubber in the glasses, it must not have any recognizable defects or even traces of mold.
4. Glasses from the dishwasher are sufficiently sterile. If you use these jars while they are still warm from the dishwasher or close them when they are warm, they will remain sterile. So you always have the right lid for the glass.
