About this recipe

Salsa mexicana cruda, also known as pico de gallo or flag salsa, is the most iconic and recognisable preparation of Mexican cooking: tomato, white onion and serrano chilli finely diced into small cubes, mixed with freshly chopped coriander, lime juice and salt. The secret lies in the precise cut - uniform 5 mm cubes - and the exact balance between the acidity of the lime, the heat of the chilli and the freshness of the coriander. Its green, white and red colours represent the Mexican flag, hence its alternative name.

History & Origin

Salsa mexicana cruda is as old as Mexican cooking itself: the combination of tomato (tomatl in Nahuatl), chilli and onion is the fundamental aromatic trinity of Mesoamerican cuisine, documented in Aztec codices and in the chronicles of Sahagún in the sixteenth century. The markets of Tenochtitlán offered this combination of fresh chopped ingredients that the Aztecs called chiltomatl. With the arrival of the Spanish, lime was added - introduced from Asia via Europe - and coriander, native to the Mediterranean, creating the definitive formula we know today. In contemporary Mexico, salsa mexicana cruda is omnipresent: it appears in taquerias, high-end restaurants, domestic kitchens and street fairs, and has conquered the world as the universal accompaniment to Mexican food.

Method

  1. 1

    Wash all ingredients thoroughly. Pat dry with kitchen paper so the cutting is clean.

  2. 2

    Cut the tomatoes into quarters, remove the seeds and excess juice to prevent the salsa from becoming watery. Dice the flesh into small 5 mm cubes.

    💡 Uniform cutting is the secret to perfect pico de gallo.

  3. 3

    Peel and dice the white onion into the same size cubes as the tomato. For a milder flavour, soak the diced onion in cold salted water for 5 minutes and drain.

  4. 4

    Slice the serrano chilli into very thin rounds or brunoise. For less heat, remove the seeds and veins.

  5. 5

    Chop the fresh coriander including the tender stalks (they have more flavour than the leaves).

  6. 6

    Combine all ingredients in a bowl. Add the lime juice and salt. Taste and adjust. Serve immediately - this raw salsa does not improve with resting.
