English Translation
"The day before, soak the cod, changing the water several times, and also soak and devein ancho chiles. The next day, grind the chiles with garlic, pepper, and clove, then fry in oil and more lard than oil. Then add water and the raw cod, leaving it on the heat until thoroughly cooked. Thicken with soaked and ground bread, and when serving, add a little oil, chopped parsley, olives, and pickled chilies."
Note on the Original Text
The manuscript’s style is conversational and assumption-based—instructions skip measurements and expect cooks to understand tactile cues: 'until it cooks well' or 'add enough water.' Punctuation is irregular and spelling reflects early 20th-century norms ('friendose' for 'friéndose'). This method speaks to a communal kitchen culture where recipes were shared orally and transcribed hurriedly. Today’s recipe translations add structure and measurements for clarity but strive to honor the spontaneity and expertise of the past.

This recipe hails from a handwritten family manuscript in Durango, dated 1914, a moment when Mexican households, especially in the north, navigated both tradition and great societal change. Recipes were passed from woman to woman, and family cookbooks like this were practical guides and cherished heirlooms. Salt cod (bacalao) was a revered Lenten and festive ingredient, and the careful sourcing, soaking, and seasoning found in this recipe reflect both global and local influences. The use of ancho chiles and the gentle thickening with bread point to a blending of colonial Spanish techniques with indigenous flavors, all set down in spontaneous, narrative style.

The original cook would have employed a sturdy molcajete (stone mortar and pestle) to grind the chiles and spices by hand, lending the sauce a special texture and flavor. Cooking was likely done over a wood-fired or charcoal stove in heavy clay or cast iron pots, while bread for thickening might be bits left from previous days. Chopping was done with simple, well-worn kitchen knives, and soaking the cod and chiles took place in earthenware bowls. A large wooden spoon stirred the bubbling pot, bringing everything together with care and patience.

Ingredients
- 1 lb 2 oz salted cod (bacalao), soaked and desalted
- 1 oz (about 4) dried ancho chiles, soaked and deseeded
- 3 garlic cloves
- 1 teaspoon (0.07 oz) black peppercorns
- 2 whole cloves
- 2 tablespoons (1 fl oz) vegetable oil
- 1 tablespoon (0.5 oz) lard (or extra oil)
- 1 1/4 cups water
- 1 3/4 oz day-old bread, soaked and crumbled
- 1 3/4 oz pitted green olives
- A small bunch (0.35 oz) fresh parsley, finely chopped
- 0.35-0.7 oz pickled tornachiles (or substitute with pickled jalapeños/guindillas)
Instructions
- Begin by soaking 1 lb 2 oz of salted cod in plenty of water overnight, changing the water several times to remove excess salt.
- At the same time, soak and seed 4 dried ancho chiles (about 1 oz).
- The next day, blend the chiles with 3 garlic cloves, 1 teaspoon of black peppercorns, and 2 whole cloves until a smooth paste forms.
- In a pan, heat 2 tablespoons vegetable oil and 1 tablespoon lard (or only oil if preferred), and fry the chile paste until fragrant.
- Add about 1 1/4 cups water and the drained, raw cod fillets to the sauce.
- Cook gently over medium-low heat until the cod is fully cooked and tender, around 20-25 minutes.
- Thicken the sauce by adding about 1 3/4 oz of day-old bread, soaked in water or milk, and crumbled into the pan.
- Stir until the sauce thickens and becomes silky.
- To finish, drizzle with a bit more oil, sprinkle generously with chopped fresh parsley, garnish with pitted green olives (about 1 3/4 oz), and serve with pickled chiles (substitute with pickled jalapeños or guindillas if tornachiles are unavailable).
- Serve hot.
