Here are cucumbers that have been in their brine for one day (left) and about one week (right). You can see that, in the jar on the right, the colors have changed and the brine has gotten cloudy. This is just what is supposed to happen. Fermentation is well under way. People often send me pictures of jars like the one on the right and ask, “Should I throw these out?” No! It’s time to taste them. Are they sour enough to your taste?
