Combine the cilantro, a pinch of salt, the garlic, and the oil in a food processor or high-speed blender. 2. Process the mixture until it's well combined, stopping to scrape down the sides of the container as necessary to ensure everything is incorporated. 3.
Add the freshly squeezed lime juice and blend for just another second to combine. 4.
Check the consistency. If you prefer a thinner sauce, add a little water, one teaspoon at a time, and pulse until you reach your desired texture. 5.
Taste and adjust the seasoning with more salt or lime juice if needed.
Serve immediately or transfer to an airtight container and refrigerate for up to 3 days.
Don't discard the tender upper stems of the cilantro! They are packed with flavor and blend beautifully into the sauce, adding more depth than just the leaves alone.
