Things to know all about preserving, canning and pickling

The WECK®-preserving-method

The normal and natural spoilage of fruits, vegetables and meat is caused by micro-organisms, which are circling through the air. During preserving, the micro-organisms are killed inside the jar. Through the heating process arises an overpressure. Glass lid, rubber ring and clamps act like an overpressure valve: they let go of air, steam and eventually liquids from the inside of the jars and nothing can get inside - no air and no cooking-water (fig. 1). During cooling process, a vacuum arises inside the jar. The clamps are now redundant and have to be removed (fig. 2). Now you can check, if the jars are closed. If the content spoils later, carbon dioxide push open the glass lid. This is a significant sign for you, which saves you for eating cluelessly spoiled food.

Preserving correctly with WECK® round rim jars

correctly preserving

(fig. 1) Fill the jar approx. 1 cm under the edge.

(fig. 2) Turn over the glass lid, so that the writings and WECK® strawberry are pointing upwards.

(fig. 3) Turn over the glass lid again and put it with the rubber ring onto the jar.

(fig. 4) Seal the lid with 2 clamps. Set.

(fig. 5) During preserving, the topmost jar (or the highest one) has to be fully covered with water. The sealing-up rubber ring prevents the incoming of water during preserving.

(fig. 6) After preserving, remove clamps. If the jar is closed tightly, the preserving was successful, the content is safe.

Preserving tips

  1. Pay attention to cleanliness. Before using, wash out jars and lids with hot water. Boil up the rubber rings with vinegar-water. Pay attention to the rim of the glass – it has to be clean before closing it.

  2. Don't use porous rubber rings. Keep an eye on jars, lids and clamps that they are not damaged.

  3. Avoid temperature differences: Put cold jars in cold water and hot filled jars in hot water. Don't put hot jars onto a cold surface.

  4. Protect your preservings from direct sunlight. Best to do: Keep them cool and dark.

  5. Follow the recipe instructions and the prescribed times and temperatures exactly.

  6. WECK round rim jars are suitable for fruits, vegetables, juices, marmelades, jellies, jams, sausage products, complete dishes and cake.

  7. Opened jars should be covered with fresh covers, storaged in the fridge and eaten quickly.

  8. Originally WECK round rim jars are temperature-resistant up to 250 degrees. They are eminently suitable for backing in jars.

  9. Appetizer & dessert are great in jars, too.

  10. With labels, ribbons and doilies, you can make an individual gift out of the modest jars.
