In a blender or food processor, combine the tomatoes, garlic, and salt. Blend until the mixture reaches a smooth consistency.
Transfer the blended mixture to a saucepan and stir in the chopped jalapeños and onion. Place over medium heat and let it simmer for 10–15 minutes, stirring occasionally, until the flavors deepen and the salsa thickens slightly.
Pour the salsa into a serving bowl and allow it to cool to room temperature. Just before serving, stir in the fresh lime juice and chopped coriander for a vibrant, zesty finish. Enjoy with tacos, grilled meats, or crispy tortilla chips.
