This Pesto is a delicious alternative to basil based Pesto. The rocket gives a delicious peppery flavour which complements many different dishes. You can try many different types of herbs to make a Pesto, why not also try making my Asian Pesto which you will find through the recipe search. This recipe makes around 250ml more than you will need for one recipe but it will store well in a jar in the refrigerator for 1 month.
