1 large yellow onion, chopped
3 cloves garlic, minced
1-2 jalapeños, minced
¼ cup neutral oil
2 pounds tomatoes, chopped
1 (12-ounce) bottle of beer
1 tablespoon brown sugar
¼ cup lime juice
¼ cup chopped cilantro
2 tablespoons tequila
Tortilla chips, for serving
Heat oil in a large saucepan over medium heat. Add the onion, garlic and jalapeños and cook for 5 minutes, stirring frequently. Add the tomatoes, beer and brown sugar. Bring to a simmer and continue simmering until the mixture has thickened, 20-30 minutes.
Add the lime juice, cilantro and tequila, then puree using an immersion blender, or transfer to a food processor or blender and puree in batches until the salsa reaches your desired consistency.
