Pickling Lime (Calcium Hydroxide)

A white, almost insoluble powder, also known as slaked lime, used in some older pickling recipes to add crispness to pickles. Due to its caustic nature, pickling lime is no longer recommended for making homemade pickles. Failure to remove lime adequately may increase the risk of botulism. Lime can also cause gastrointestinal problems if too much is ingested.
