If you are a sourdough bread baker you may want to try using a calculated amount of pickle brine in a light rye with caraway. How much brine to use depends on the the percentage of salt in your brine solution. For my brined pickles I use 4% sea salt. That equals 4g of salt for every 100g of water. Depending on how much water or liquid and salt my particular recipe requires I can determine how much brine provides that salt and use water for the balance. If my recipe, for example, requires 12g of salt and 400g water. I could use 300g brine and 100g water and fulfill the 12g of salt I need and the total 400g water. That's a lot of brine use.
