Wash the fresh cilantro bunch and cut off any long stems.
Place the washed cilantro, 3 cloves of garlic, 1/4 cup of lime juice, 1 fresh jalapeno, (with the stem and seeds cut out) and 1/2 teaspoon of salt in a food processor
Blend until all ingredients are finely chopped, then slowly add 1/3 cup oil while the food processor is running. Scrape the edges if needed and blend until creamy.
