Pickle Pipe - One-Piece Silicone Waterless Fermentation Airlock Lids for Mason Jar Fermentation - Regular Mouth - 4 Pack

These fermenting lids work great. I have a set of the wide mouth jar ones and they work so well that I purchased these regular mouth jar ones. Currently being used for my fermented ketchup that has a tendency to burn it a regular jar lid is even slightly too tight. Since they are silicone, they are non staining and I don't have to worry about outgassing or the acidy ferments damaging them and ruining my fermenting. They are way easier to use than standard fermenting lids. If I am making multiple versions of a certain ferment I can colour code it with the coloured lids based on the recipe I am using. Highly recommend.

Permite usrlos en los botes de Mason Jar, permiiendo que respire sin tener que abrir el bote, totalmente recomendable, estoy entusiasmada

I had never tried fermenting anything but I wanted to make Kimchi. I bought these and some mason jars and Googled some instructions and recipes. These things make it so simple that now I’m fermenting everything, including blackberries. I kept hearing about exploding jars and mould - nothing! They take care of themselves. I just filled them, stuck a shot glass in to press everything down, and left them for a week. I bought the smaller size but I will be buying more of both sizes. Really great product and really easy to clean.

Perfetto

Easy to use, works as described.
