The Kilner Fermentation Set provides an easy way to create large batches of your own delicious fermented foods packed with vitamins, minerals and probiotic cultures. Perfect for creating sauerkraut, kimchi, pickles and much more. Creating your own fermented foods is easy - just add your favourite vegetables, filtered water and salt. This set includes one Kilner 5 Litre Fermenting Jar, one glass weight, one air lock, one silicone lid, one silicone sheet and one recipe/ instruction booklet. The silicone lid with air lock, allows gas to be released but does not allow air to enter the jar during the fermentation process. The clever design of the silicone sheet and glass weight, ensures that the contents are submerged under the brine to prevent any spoilage. Made from high-quality sodalime glass with pristine clarity and consistent wall thickness ensuring no weak points, this set is hand wash only. Kilner glass is made from natural ingredients so no harmful chemicals or toxins can leak into the food. Glass is BPA-free and does not absorb odours, flavours or stains. Not only is glass a healthier option, but it is also made to last and never for single use. Kilner continues to tackle plastic waste with our ethos of REUSE, REFILL, RECYCLE. The original Kilner Jar, invented by John Kilner and Co. in England is as much loved and successful now as it was over 180 years ago. Our diverse product range provides simple solutions for preserving, food preparation, storage and eating on-the-go using high quality materials all authenticated with the iconic Kilner brand logo.
