Fermented Pico de Gallo

This dish involves chopping fresh tomatoes and onions, then allowing them to ferment slightly at room temperature for extra depth of flavor. The key ingredients—tomatoes, onions, jalapeños, lime, and salt—combine through natural fermentation, resulting in a tangy, slightly bubbly pico that develops a layered complexity. The final texture is vibrant and slightly softer than fresh pico, with a visible fermentation appearance and a subtle tang.
