For preserving using the traditional WECK® method you need WECK® accessories such as a rubber ring and two original WECK® clamps per jar. There are rubber rings for all mouth sizes of WECK® jars. Before use they should be cleaned in hot water (without any detergents, preferably with a splash of vinagre). The clamps are suitable for all jars and can be reused as often as you like. More WECK® accessories are filling funnels and WECK® jar lifters that are useful to get the jars out of the hot water. The WECK® cookbook offers you detailed information about preserving and several recipes for sweet, sour and savoury delicacies. With some WECK® jars and the appropriate WECK® accessories anyone is able to preserve easily. You may find more information and recipes at www.einkochwelt.de/en/nice-to-know.
