Every real housewife knows that it is significant to sterilize jars for the winter, if it is not done properly, the full process of making jams and ajvar can go to waste.

Our grandmothers used a simple, but also good technique, which is still reliable today.

1st Method Sterilization:
  1. The first step is to wash the jars well with detergent, and then dry them with a clean cotton cloth. Before sterilization, the jars should be thoroughly rinsed and the cracks in the neck, walls, and bottom checked.

  2. Even the slightest damage can lead to the jar bursting and breaking completely after a while.

  3. After that, take a large baking tray, cover its bottom with baking paper and then arrange the glass bowls next to each other, so that their top will be turned down.

  4. Before that, of course, you removed the lids, which are redundant in this “operation”. Preheat the oven to 100 degrees and put the baking tray in it.

  1. Rinse the jar with a mixture of water and alcohol. In a jar half full of water, add two tablespoons of alcohol, close them and shake well. Alcohol will clean and sterilize the inside of the jar, while you can wipe the outside with a clean cloth soaked in alcohol.

  3. Bottles and jars should never be completely filled, because that accelerates the spoilage of the winter.
