What do nasturtium leaves taste like or similiar to?

I love what Helen'sAND shared. In my mouth nasturtium don't take like capers at all, not that I am against capers. Of course I am one of those people who experience cilantro tasting like soap.

Thank you both! I'm a huge fan of capers and I pickle everything. I will add to my food list. : )

They are similar to capers, but not tart since they are not pickled. They are wonderful. The flower buds can be pickled like capers. I believe the whole plant is edible.

They have a delightful peppery taste and are light. Love them!
