Can you substitute pickling salt for kosher salt?
If you need the salt to kosher meat then yes, so long as it absorbs all traces of blood from the meat. If you’re using a recipe that requires kosher salt, however, it might be best not to – since kosher salt has larger granules than other types of salt, it reacts differently during cooking and so the recipe may taste different once cooked. Coarse sea salt can be used instead.
