Wash the cilantro and shake it dry. Trim off the ends, then cut the cilantro into the food processor bowl.

Wash the lemon and cut into eighths, removing any seeds. Add to the food processor.

Crush the garlic cloves with the flat blade of a chef's knife to make it easier to remove the papery husks.

Add the garlic, walnuts, and curry powder to the food processor. Blend, stopping to scrape down the sides once or twice. You may need to add some additional lemon juice or olive oil if the lemon is not very juicy or your ratio of drier ingredients is higher.

Serve as a dip or spread.
