Thick peanut salsa with toasted arbol chilli. Complex, aromatic Oaxacan flavour.
About this recipe
Peanut salsa is a thick, aromatic salsa from Oaxaca that combines toasted peanuts with dried arbol chillies, garlic and roasted tomato. Its complex flavour blends the smokiness of chilli with the creamy, slightly sweet peanut. Ideal for tacos, tlayudas and memelas.
History & Origin
Peanut salsa has its deepest roots in Oaxaca, land of the seven moles and of an extraordinarily rich and diverse salsa tradition. The peanut, native to South America but adopted by Mesoamerican cultures thousands of years ago, was cultivated extensively in the Oaxacan valleys long before the Spanish arrived. The Zapotecs and Mixtecs were already preparing salsas and pastes from toasted peanuts combined with local chillies, a tradition that survives intact to this day. This particular salsa is the most popular of the Oaxacan peanut salsas: it is made by toasting shelled peanuts on a griddle until golden, together with dried arbol chillies that are toasted until dark and release their pungent aroma. Everything is ground in the molcajete or blender with roasted tomato, garlic and a little water, creating a salsa with a thick, slightly grainy texture that is utterly addictive. In the markets of Oaxaca, particularly the Mercado 20 de Noviembre and the Mercado Benito Juarez, this salsa is served in clay bowls alongside tlayudas, tasajo and cecina. Its flavour is complex: the natural sweetness of peanut, the heat of arbol chilli and the smoky touch of toasting combine in every spoonful. It is a salsa that transcends borders and wins ever more admirers outside Oaxaca.

Method
- 1
Toast the shelled peanuts in a dry frying pan over medium heat, stirring constantly, for 5 minutes until golden and aromatic. Set aside.

💡 Be careful not to burn them: they go from toasted to burnt in seconds.
- 2
In the same pan, toast the arbol chillies for 1-2 minutes until slightly darkened and fragrant. Do not burn them.

- 3
Char the tomato and garlic (with skin) on a dry griddle or pan until well blackened on all sides, about 8-10 minutes.

- 4
Peel the charred garlic. Place the toasted peanuts, arbol chillies, charred tomato, garlic and salt in the blender.

- 5
Add half a glass of water and blend until you have a salsa with a slightly grainy texture. It should not be completely smooth.

💡 If you prefer the traditional molcajete texture, grind everything in a mortar instead of using the blender.
- 6
Taste and adjust salt. If too thick, add a little more water.

- 7
Serve at room temperature. This salsa improves after resting for 30 minutes and keeps well refrigerated for up to 5 days.
