The 1 Litre Kilner Fermentation Jar Set provides the easy way to create smaller batches of your own delicious, fermented foods packed with vitamins, minerals and probiotic cultures. The wide neck opening on the jar allows for easy filling and decanting of the finished creation. The unique silicone duck beak shaped valve incorporated in the lid releases the gases that build up inside the jar during the fermentation process. However, the atmospheric air on the outside will not be able to enter the jar, which usually causes food to spoil. The ceramic weights sit on top of the ingredients to ensure that they are kept under the brine solution. Once fermentation is complete, the one-piece lid allows you to store the finished food in the fridge ready to consume. Packaged in a full colour gift box with recipe and instruction booklet, ideal for gifting. The jar is suitable for the dishwasher. Lids need to be hand washed and dried immediately.
