I carry an apple to work every day with black pepper & salt pouches from Taco Bell, & my american co-workers have asked me why I sprinkle salt on fruit? I explain them we sprinkle salt on apples, banana, guava, pineapple, watermelon, cucumber, tomatoes, onion, oranges and many other things.

Black salt is not tangy like lemony, it is just rock salt. Sometimes fruitsalts are salts peppered with ground black pepper and or lemon juice. Black salt on its own is earthly salty like ocean water.
