Nasturtium (sounds yummy? Not!) is part of the watercress family whereas capers are the pickled immature flower buds of Capparis spinosa, the caper bush. What did people do before the internet?
So, I looked them up and it seems I have eaten them before in a bean salad sort of dish and did not realize they were not a bean. I learned that 100 grams (almost 4 oz. which I think is a lot) has 23 calories and 2,348 mg of Sodium. I’m swelling up just reading about them!
They are generally used as a seasoning. No worries ;-)
Capers are the buds, and I can take them or leave them. Nasturtium leaves and flowers are edible, with a clean peppery sort of taste, and really good in salads. They also repel certain bugs, so I interplant them with my broccoli and munch on them during the spring. :)
