Molcajeteado: salsas and guacamoles worked in volcanic stone

What is it?

Molcajeteado is the traditional Mexican technique of preparing salsas, guacamoles and pastes by crushing ingredients in a molcajete (volcanic stone mortar). Unlike the blender, which pulverises homogeneously, the molcajete crushes by pressure and friction, leaving a rustic texture with distinguishable pieces and releasing essential oils from chillies, garlic and seeds. The result are salsas with more body, deeper flavour and aromas that stand out on the palate. Classic products of molcajeteado include guacamole with tomato and chilli, the molcajeteada salsa of chile pasilla or morita, green salsas of tomatillo and, in some regions, pipianes and homemade moles. It is a living technique in Mexican kitchens, from eateries to fine-dining restaurants.

Origin and history

The use of the stone mortar to crush food is pre-Hispanic and is documented from at least 6,000 years ago in Mesoamerica. Bernardino de Sahagun in the 16th century describes in his Historia general the practices of grinding chillies, tomatoes and seeds in stone. The molcajete (from the Nahuatl molcaxitl: vessel for salsa) and its tejolote (pestle) are a direct heritage of Mexica cuisine, where the salsa or chilmolli was an essential accompaniment to tortillas and meats. After the conquest, the molcajete survived the arrival of European mortars due to its functional superiority and particular texture. For centuries it was the unique way to make salsa until the mass adoption of the blender in the 20th century. Larousse Cocina and various documentary sources record that molcajeteado is considered a Mexican heritage technique, and various regional traditions (Oaxaca, Guerrero, Puebla, Mexico City) preserve it alive with their own variants.

Characteristic ingredients

The molcajete process requires prior preparation: the new molcajete is cured by grinding several batches of rice, salt and garlic until it stops releasing grit. To make a typical molcajeteada salsa, the ingredients are first roasted on a comal: tomato, tomatillo, garlic, onion and dried chillies lose water and develop toasted flavour. Then they are crushed in the molcajete in order: first garlic and salt (which act as abrasives), then chillies, then tomato or tomatillo. The technique is to press while rotating the tejolote, not to crush vertically. The final texture should be rustic: visible pieces bound by juices and oils. For guacamole, avocados are mashed at the end, mixing them with the molcajeteada base of chilli, onion and coriander. The difference from the blender is notable: the molcajete releases volatile oils and leaves chilli microparticles that give sensory texture, while the blender homogenises and oxidises faster by incorporating air.

Cultural significance

Molcajeteado is a daily cultural practice in traditional Mexican kitchens and forms part of the intangible gastronomic heritage recognised by UNESCO in 2010. Making the salsa in molcajete is a social moment: the sound of the stone announces the meal and many diners appreciate that the salsa arrives at the table in the molcajete itself, in a rustic and steaming version. Some traditional restaurants such as Oaxacan eateries, Mexico City taquerias and rural canteens serve molcajeteada salsa as a hallmark of quality and authenticity. Molcajeteado guacamole at the table, popularised by Mexican restaurants in the United States and Europe, has made the molcajete an international symbol of Mexican cuisine. In contemporary cuisine, Mexican chefs use it as a signature technique to underline the manual and artisanal character of their preparations, distinguishing them from homogenised industrial cuisine.

Frequently asked questions

What is the difference between molcajeteada salsa and blender salsa?

Molcajeteada salsa has a rustic texture with visible small pieces, deeper flavour due to the release of essential oils and an unpulverised point that makes it more interesting on the palate. Blender salsa is more homogeneous, light, oxygenated and is usually more liquid; it loses nuances of chillies and garlic due to the excessive cutting of the blades.

What does a molcajeteada salsa taste like?

It has a concentrated flavour of roasted chillies, toasted garlic, caramelised tomato and mineral notes provided by the volcanic stone of the molcajete. It is more intense than blender salsa, with chewable body and depth of aromas. Its smoky character comes from the previous roasting of the ingredients on the comal.

How is a molcajeteada salsa served?

It is traditionally served in the molcajete itself, brought hot to the table with totopos, hand-made tortillas or tacos. Some regions add melted cheese or strips of cecina to serve it as a snack. Molcajeteado guacamole is prepared and served directly in the molcajete with coriander and diced onion.

Where does molcajeteado come from?

Molcajeteado originates from Mesoamerica, with archaeological evidence of the use of the molcajete dating back 6,000 years. Today the technique is practised throughout Mexico with regional variants: chile pasilla molcajeteada salsa in Mexico City, morita salsa in Veracruz, molcajeteado guacamole throughout the country and molcajeteado pipianes in Oaxaca and Puebla.
