To make garlic scape pesto, first you will need to wash and trim any of the tough ends off the garlic scapes. Then chop the scapes into small bits. I prefer to chop into smaller sized pieces as there is less chance of stringy bits forming in the pesto.
Add the scapes to a food processor or a blender.
Add the walnuts, 6 TBSP (90ml) of olive oil, and lemon juice to the food processor or blender.
Pulse until everything is finely chopped. Add more olive oil, if needed.
Add the basil leaves and blend the mixture on low until it has reached the desired consistency. At this point, if you think the mixture is a little too dry (this can happen when using larger, more mature scapes), you can add a little bit of water if desired.
Add the salt and pulse to mix. Taste and add more salt and lemon juice as desired.
Store in an airtight container in the fridge or in a freezer safe container in the freezer.
