Preserving in the pot: Prepare glasses
Before you start preserving, you should prepare your jars and the contents well.
- First, the glasses must be sterilized. You can do this in different ways.
- It is important that the glasses are treated at least 100 degrees Celsius. This kills all germs and bacteria.
- To ensure that your glasses do not shatter when they are filled, place them on a damp tea towel after sterilizing.
- Then fill the glasses with the prepared jam or vegetables. Make sure that about two to three centimeters remain free from the top edge of the glass.
- Close the jars immediately after filling.
Preserving jars: Here’s how
To preserve your glasses in the pot, you need a large pot and a wire rack.
- Place a grid in the pot. Your glasses must not stand on the bottom of the pot when preserving. If you don’t have a grid, you can put a kitchen towel on the bottom of the pot instead, for example.
- Place the glasses in the pot and fill it with water.
- Bring the water to a boil. Ideally, this should have the same temperature as the contents of the glass.
- Otherwise, your glasses may shatter. It is best to check the water temperature with a thermometer.
- The preserving time begins as soon as bubbles appear in the jar.
- If the preserving time specified in the recipe is long and the water evaporates quickly, add a little more water.
- After the preserving time, take the jars out of the pot and let them cool down.
