Tacos de escamoles
Tacos de escamoles are tacos filled with escamoles, the edible larvae and pupae of Liometopum ants, typically sautéed in butter with onion, chile and epazote. A pre-Hispanic delicacy of the central highlands, escamoles are harvested only in spring and command high prices, earning the nickname 'Mexican caviar'.
Escamoles
Escamoles are the larvae and pupae of ants of the genus Liometopum. The Larousse culinary dictionary names Liometopum apiculatum and L. occidentale and describes the larvae as creamy white, resembling puffed rice, dug from underground nests and prized for their delicate flavor and high protein content. México Desconocido derives the name from the Nahuatl azcatl, ant, and molli, sauce or stew, and calls the dish a pre-Hispanic food of central Mexico, harvested in Tlaxcala and in Hidalgo, where it describes collection at San Agustín Tlaxiaca.
The season is short. Larousse gives March to April and México Desconocido March to May, which places escamoles at the heart of the Lenten season.
Harvest
México Desconocido describes a full day of hand digging in the sun, with harvesters working carefully to avoid crushing the larvae while being bitten by the ants. Done properly, a nest can be harvested up to three times a year, but untrained collectors who overharvest destroy colonies. The scarcity and labor involved explain the high price. After collection the larvae are washed to remove soil and debris.
Cooking and tacos
The best-known preparation is a quick sauté. México Desconocido's method cooks the washed escamoles in oil and butter with onion, adds chopped serrano chile, seasons with salt and epazote and cooks only a few minutes; it also mentions versions a la mexicana, with tomato, onion and chile, and al ajillo, with garlic. Larousse lists escamoles cooked in a turkey-egg omelet, in mixiote and in a 'mole de hormiga' with chile sauce, nopales and epazote. The buttery sauté is served in warm corn tortillas, often with guacamole or a mild salsa so the escamoles themselves are not masked.
Handling
Escamoles are delicate. Before cooking they are rinsed in repeated baths of water to remove soil and ant debris, a step that requires care so the soft larvae do not break. They need only a few minutes over heat, since prolonged cooking toughens them, and México Desconocido notes that they turn white once cooked. Because they are costly and seasonal, they are usually seasoned lightly, with butter, onion, chile and epazote, so that the ingredient itself remains the focus of the taco.
Recipe
Ingredients
- 250 g fresh or thawed escamoles
- 2 tablespoons butter
- 1 tablespoon oil
- 1/4 white onion, finely chopped
- 1 serrano chile, finely chopped
- 2 sprigs epazote, leaves chopped
- Salt
- 6 small corn tortillas
- Guacamole for serving
Steps
- Rinse the escamoles gently in a fine sieve, handling them carefully so they do not burst. Drain well.
- Heat the butter and oil and cook the onion until translucent.
- Add the chile and cook 1 minute.
- Add the escamoles and epazote and cook, stirring gently, 3 to 4 minutes, just until heated through and opaque. Season with salt.
- Serve immediately in warm tortillas with guacamole.
Overcooking makes escamoles dry and rubbery. Buy from reputable sellers who harvest sustainably.
