If you don’t have a pestle and mortar, you can use a blender or food processor instead.
ALTERNATIVE FLAVOUR COMBOS:
– Use half basil and half rocket, replace the pine nuts with walnuts, and use pecorino instead of Parmesan to keep things veggie.
– Swap out pine nuts for almonds and basil for rocket.
– Use hazelnuts in place of pine nuts and replace basil with flat-leaf parsley.
– Go for an Asian vibe and use cashews, coriander and a squeeze of lime.
