This recipe was adapted from one I found on google. There is a commercial dip of rocket/cashew nuts that I like, so I tried cashews but the walnuts were nuttier and more peppery so I'll stick to them in future.
3 cups rocket
4 cloves garlic
1/3 cup walnuts, toasted
1/3 cup parmesan, grated
200 ml olive oil
Whiz the first 4 ingredients in the food processer, till chopped, then slowly pour in the olive oil.
Most of what I made was frozen, for using on pasta and as dip when summer is gone.
