Gather all ingredients: jalapenos, pine nuts, cilantro, garlic, salt, and olive oil. Rinse cilantro and jalapenos. Remove seeds and ribs from jalapenos if desired.

In a food processor, combine chopped jalapenos, pine nuts, cilantro, garlic cloves, and a pinch of salt. Pulse until coarsely blended.

While food processor is running, gradually drizzle in olive oil, scraping down the sides. Blend until creamy.

Transfer pesto to a clean container. Serve immediately or seal for storage.
