How to make nasturtium pesto

Last year we grew nasturtiums on the allotment as a food crop. They have a habit of spreading and smothering everything in sight. This year we didn't plant any but we still have plenty of them! So we have been harvesting nasturtium leaves for use in salads and soups. However, I had been planning to make nasturtium pesto so in this video I have a go at making it.

It turned out to be rather tasty. Our plan had been to use it on some pasta but we decided instead to put it on some boiled new potatoes from the allotment. Very nice!
