I started a 20# bucket of cucumbers brining last week (5/25 for reference sake). There is a nice scum starting to form on top of the brine which is a good sign. Also, there are nice little lacto-fermented bubbles starting to come to the surface. Won't be long before we will have pickles. This process will take between 4 and 6 weeks. Then I will de-salt the cukes and then make the pickles.
