I know the difference between black pepper and white pepper is:

1, the flavor is different

Black pepper has a much stronger flavor than white pepper, and white pepper has a bit more pungent flavor than black pepper.

2, made of different ingredients

Black pepper is made of unripe pepper berries,

White pepper is made of peeled pepper seeds

3, different uses

Because white pepper and black pepper have different flavors, their uses are also different.
