Just last year I learned about cutting celery.
Amazing and extremely hardy plant.
I had never heard of 'cutting celery'; turns out to be 'Asian leaf celery'.
While looking around for more info, I checked Wikipedia for celery, and found this: Similarly, combinations of celery powder and salt are used to flavor & preserve cured pork[28] and other processed meats as an all natural alternative to industrial curing salt.[29] The naturally occurring nitrites in celery work synergistically with the added salt to cure food.
