Mexico City market tacos of pork womb in smoky morita chile sauce.

About this recipe

Tacos filled with pork womb braised in morita chile and tomato sauce. A popular offal dish from Mexico City markets with an intense flavour and unique texture.

History & Origin

Tacos de nana are one of the most authentic dishes of Mexican offal culture. In Mexico City, butcher stalls and market stands that specialise in viscera and unconventional pork cuts are fundamental to the popular gastronomic landscape. "Nana" is the colloquial name in Mexico for the pork womb or uterus. Mexican offal cooking has roots in both pre-Hispanic indigenous traditions - where using the whole animal was a subsistence practice - and Spanish influence, which also has a long tradition of cooking viscera and "lesser" cuts. The result is a nose-to-tail gastronomy that has generated some of Mexico's most flavourful and identity-defining dishes. In Mexico City's historic markets - La Merced, Jamaica, Medellín - offal taco stalls open from the early hours. Tacos de nana, alongside tripe, lung, stomach and gizzard tacos, form part of the daily breakfast of many chilangos. They are braised in morita chile sauce - that characteristic smokiness - and served in small tortillas with onion, cilantro and green salsa. The flavour of tacos de nana is intense, slightly gelatinous with that soft, almost buttery texture that distinguishes them. Not for every palate, but those who try them often become devoted fans.

Method

  1. 1

    Thoroughly clean 600g pork womb: remove excess fat, wash several times in cold water and squeeze with lime juice. Cut into medium pieces.

    Step 1

    💡 Lime helps eliminate the strong odour; leave to rest 15 minutes with the juice.

  2. 2

    Simmer the womb in water with salt, half an onion, 2 garlic cloves and oregano for 45-60 minutes until tender. Drain and reserve the cooking stock.

    Step 2

    💡 Check with a fork; it should be soft but with some texture.

  3. 3

    Char-roast 4 morita chiles, 3 tomatoes and half an onion on a griddle. Blend with 2 garlic cloves and 1 cup of cooking stock. Strain through a sieve.

    Step 3

    💡 Morita chile gives the characteristic smokiness of this dish.

  4. 4

    Heat 1 tablespoon oil or lard in a pan. Fry the salsa for 5 minutes. Add the finely chopped womb. Season with salt, cumin and pepper. Cook for 15-20 minutes until the sauce is well integrated.

    Step 4
  5. 5

    Warm small corn tortillas on a griddle. Serve the tacos with the womb stew. Accompany with chopped white onion, fresh cilantro, green salsa and limes. Salt to taste.

    Step 5

    💡 Tortillas must be freshly made and very hot for these tacos.

Frequently asked questions

What people ask about this recipe

What is nana in Mexican tacos?

Nana is the pork womb (uterus), a delicacy in Mexico City street food culture. It is slow-cooked until tender and thinly sliced for tacos. Despite the name, it is a clean, lean cut with a delicate flavour, similar to lean pork shoulder but softer.

What part of the pig does nana come from?

Nana comes from the sow's reproductive tract — specifically the uterus. It is one of the 'unusual cuts' or 'tacos de canasta' offal cuts, alongside buche (stomach), cuerito (skin) or moronga (blood sausage). It is considered white offal and, when properly cleaned and cooked, has no strong taste.

What does pork nana taste like?

The flavour is mild, neutral and slightly milky, with a texture between gelatinous and firm when properly cooked. It lacks the strong taste of other offal (like liver or kidney). In Mexican taquerias it is served with onion, coriander, green salsa and lime, which give the taco its character.

Where can I buy pork nana in the UK?

Nana is not common in UK supermarkets, but Asian, Polish or Latin American butchers in London, Manchester or Birmingham often carry pork offal cuts. Ask for 'pork uterus' or 'sow's matrix' and order in advance. Halal butchers do not stock pork, but Eastern European or Latin shops are your best bet. As a substitute, use pork cheek or lean pork shoulder.

Is it safe to eat nana?

Yes, provided it is cleaned thoroughly and cooked to a safe internal temperature (at least 75°C / 165°F). In Mexico it is everyday food. Buy from a trusted butcher, clean it well with cold water, salt and lime juice or vinegar before cooking, and simmer for at least 1.5 hours until completely tender.

What is the difference between nana, buche and cheek?

Nana is the womb, buche is the stomach lining and cheek is the facial muscle. All three are common 'tacos de canasta' fillings but have different textures: nana is the softest, buche is more gelatinous with fat, and cheek is more fibrous and collagen-rich. Mexican taquerias often serve them as a mixed plate.
