Place finely chopped basil and mint in a mortar together with salt, pepper, minced raw garlic and lemon juice and give it a good bash, until herbs are completely limp and covered in the juices.
Step 2
Add pine nuts, smash them roughly, but don’t turn them into a paste. Some chunky bits are perfect.
Step 3
Put your pestle away and using a spoon, mix in oil, cheese and black garlic until just combined. Reserve. (Store refrigerated, but remove from the fridge early enough so that the pesto comes to room temperature before you toss it with hot pasta.)
Step 4
Set the pasta to boil as per instructions on packaging. When ready, drain and toss your steaming pasta with pesto and baby arugula. Plate up and scatter serving garnishes over.
