Let me tell you what I like about this pesto. First of all, it really has a kick in the flavor department. It is relatively cheap to make. It is off the chart in the versatility of uses.
If you love Wasabi... you sure love its distant cousin - the Chinese Mustard Cabbage aka Gai Choi. It's a favorite in soups and stir-fries but mostly known as pickled mustard leaves-salted or sweetened.
