Tacos al pastor

Mexico City's greatest street taco: achiote and cumin-marinated pork from the vertical spit, a fusion born of Lebanese shawarma and the Mexican market

Origin: Mexico City, Mexico

From the journey of Cumin.

Al pastor, meaning 'shepherd style', is one of Mexico City's most iconic street foods, and its origin story is a case study in culinary migration. Lebanese immigrants who arrived in Mexico in the early 20th century brought with them the vertical rotisserie technique of shawarma; Mexican taqueros adapted it to marinated pork with dried chilis, achiote, and cumin, and placed a slice of pineapple on top of the trompo (spit). Cumin is the critical bridge between the two traditions, present in both the Arab shawarma marinade and the Mexican chilli paste, binding an entirely new dish out of two ancient ones. The home method uses a roasted pork shoulder to achieve the same caramelised, crisp exterior.

Ingredients

Meat

  • 1.2 kg pork shoulder, sliced 1cm thick

Marinade

  • 3 dried guajillo chilis, stems and seeds removed
  • 2 dried ancho chilis, stems and seeds removed
  • 2 tbsp achiote paste (recado rojo)
  • 1.5 tsp ground cumin
  • 1 tsp dried oregano (Mexican)
  • 4 cloves garlic
  • 3 tbsp white wine vinegar
  • 1 tsp salt
  • 4 rings fresh pineapple

To serve

  • 16 small corn tortillas, warmed
  • 1 small white onion, finely diced
  • handful fresh coriander leaves, chopped

Method

  1. Toast the dried guajillo and ancho chilis in a dry pan over medium heat for 30 seconds per side until fragrant. Place in a bowl, cover with boiling water, and soak for 20 minutes until softened.
  2. Drain the chilis and blend with achiote paste, cumin, oregano, garlic, white wine vinegar, salt, and 3 tbsp of the soaking liquid until completely smooth.
  3. Coat the pork slices thoroughly in the marinade, massaging it into every surface. Layer the pork in a container with pineapple rings. Cover and refrigerate overnight, or at least 4 hours.
  4. Heat the oven to 200°C. Stack the marinated pork slices in a tight pile on a baking rack set over a foil-lined tray, pressing the layers together to form a compact cylinder. Place a pineapple ring on top.
  5. Roast for 1 hour 45 minutes, basting with the pan juices every 30 minutes, until the exterior is deeply caramelised and charred at the edges and the pork is cooked through.
  6. Remove from oven and rest for 10 minutes. Slice thinly across the grain using a sharp knife, then chop into small pieces. Dice the roasted pineapple.
  7. Warm the corn tortillas directly over a gas flame or in a dry pan. Layer two tortillas per taco (the traditional street style). Top with chopped pork, a piece of pineapple, diced white onion, and fresh coriander. Serve immediately.

Notes

True taquero al pastor is made on a trompo (vertical rotisserie) that holds 20–30kg of marinated pork and spins for hours. The home oven method produces genuinely excellent results if you replicate the key steps: overnight marinating, layered stacking for moisture, and a final high-heat blast for caramelisation. Leftovers keep for 3 days and reheat beautifully in a hot cast-iron pan.

Spices & AromaticsApiaceae

🌍Origin

The Levant and Upper Egypt — c. 3000 BCE

🌱Domestication

Cumin (Cuminum cyminum) is one of the oldest cultivated spices in the world, a plant whose recorded history stretches back more than four millennia and which can be followed, almost without interruption, from the clay tablets of Sumer to the spice jars of the modern supermarket. It is a slender annual of the carrot and parsley family, the Apiaceae, native to the eastern Mediterranean and southwestern Asia, growing perhaps half a metre high and bearing the small, pale, umbrella-like flower heads typical of its kin. What matters is its seed, or more properly its dried fruit: the little elongated, ridged, boat-shaped grains, brown and aromatic, that carry the warm, earthy, faintly bitter, penetrating flavour for which the spice has been prized across the whole of the Old World and, since the sixteenth century, the New. The antiquity of cumin's cultivation is exceptional even amongst the ancient spices. Seeds identified as cumin have been recovered from Syrian Bronze Age sites dating to the second millennium BCE, and the spice appears in Egyptian pharaonic tombs amongst the provisions and ritual offerings interred with the dead, valued highly enough to accompany kings into the afterlife. The Akkadian name kammūnu, recorded in cuneiform on tablets from the Mesopotamian city-states of the third millennium BCE, is the earliest documented name for cumin in any language and one of the earliest names for any spice in recorded history; it is a word that, astonishingly, still echoes in the Arabic kammūn and the Hebrew kammon spoken in the same region today, a single thread of speech unbroken across five thousand years. Unlike many spices, whose use was confined to a single role, cumin served the ancient Near East simultaneously as a flavouring, a medicine, and a ritual substance. The Mesopotamian cook ground it into stews of lamb and lentil; the Egyptian physician dissolved it into draughts for the complaints of the stomach; the temple priest set it amongst the offerings of the altar. This breadth of use, attested in Mesopotamian, Egyptian, Greek, and later Arabic texts alike, is part of what makes cumin's documentary record so unusually rich and so unusually continuous. It is, with very few rivals, an ingredient whose entire journey from wild plant to globally traded commodity can be traced across the written history of civilisation, and which has never, in all that time, fallen out of use. Wild stands of the plant in the eastern Mediterranean were almost certainly gathered long before deliberate sowing began, but by the dawn of writing cumin was already a cultivated crop, a traded good, and a fixture of the kitchen, the apothecary, and the shrine.

Global Voyage

From its Fertile Crescent origins, cumin spread in every direction across the ancient and medieval worlds, carried by traders, armies, pilgrims, and colonists until it had reached almost every cuisine on earth. The first movements were westward and eastward together. By the second millennium BCE the spice had passed into Egypt and, in time, into the classical Mediterranean world of Greece and Rome; by the first millennium BCE it had travelled east into Persia and along the nascent Silk Road into India and Central Asia, where the Sogdian merchant networks that dominated the overland trade carried it between the borders of China and the eastern Mediterranean. Each of these journeys followed the established arteries of antique commerce: the caravan road, the river valley, and the coastal sea lane down which all the costly small goods of the ancient world travelled. The classical Mediterranean made cumin a fixture of its tables and its medicine. Greek and Roman physicians, amongst them Hippocrates, Dioscorides, and Pliny the Elder, documented at length its supposed virtues as a carminative and a remedy for the stomach, whilst Pliny records that in the Roman kitchen cumin was the favourite table condiment, kept in little boxes beside the black pepper so that diners might season their own food. Roman legions carried it to the frontiers of the empire, and its traces have been found in military camps in Britain and along the Rhine, the spice of a soldier's ration far from home. Through Greek and Roman medicine, cumin entered the Western pharmacopoeia and persisted in European physic throughout the medieval centuries. The most decisive chapter of cumin's voyage was the Arab expansion of the seventh to ninth centuries CE, which carried the spice, along with Islam and the agricultural science of the Fertile Crescent, across the whole of North Africa and into the Iberian Peninsula. The Abbasid cookbooks of Baghdad codified its place at the heart of Islamic cookery, and in the Maghreb it became the defining aromatic of the regional kitchen, the structural note beneath chermoula, harissa, and the spice blends of the tagine and the couscous pot. From North Africa it passed south, too, along the Red Sea and the trans-Saharan routes, into the Horn of Africa, where it became one of the constituent spices of the Ethiopian berbere blend. The final great movement was colonial and oceanic. In the sixteenth century Spanish colonisers carried cumin across the Atlantic to Mexico and South America, where it met the indigenous traditions of dried chilli, tomato, and corn and fused with them so completely that within a generation it had become inseparable from the cooking of the Americas, the warm backbone of Mexican guisados, of the Colombian hogao, of the Argentine locro, and at last of the Tex-Mex chilli of the United States. Today India produces roughly 70% of the world's cumin and accounts for most of its consumption, with Gujarat the global capital of the spice; the Indian subcontinent and North Africa together account for the majority of global cumin use, making cumin the second most widely traded spice after black pepper. From a wild herb of the Levantine hills to the second most traded spice on earth, cumin has followed the human migrations of five thousand years.

🍽Modern Culinary Role

Cumin is the world's second most widely traded spice after black pepper, and across a vast belt of the globe it is one of the indispensable foundations of savoury cooking. It is the aromatic backbone of the cuisines of India, Mexico, the Middle East, North Africa, and Central Asia, the warm, earthy, faintly bitter note that anchors a whole architecture of spice blends and sauces: it is fundamental to the curry powders and garam masalas of the subcontinent, to the harissa and chermoula of the Maghreb, to the berbere of Ethiopia, to the chilli con carne and tacos al pastor of the Americas, and to the kebab and the plov of the lands between. Few spices are used so widely, and fewer still are used in such quantity, for cumin is rarely a delicate accent but rather a structural ingredient, present by the spoonful rather than the pinch. Its forms and uses are as various as its geography. In the Indian kitchen whole cumin seeds are tempered in hot oil or ghee to release their fragrance at the start of a dish, the technique of the tarka, whilst roasted and ground cumin is dusted over yoghurt drinks, chaats, and salads; in the Mexican and Tex-Mex kitchen it is ground and toasted into the chilli pastes and bean dishes; in Central Asia whole seeds are toasted in lamb fat for the great rice dish of plov; and in North Africa it is blended into the dry spice mixtures that season nearly every savoury preparation. The contrast between the whole-seed traditions of India and Central Asia and the ground-spice traditions of the Americas and North Africa is one of the defining distinctions of world cookery. Cumin has, moreover, never wholly shed its ancient medicinal reputation. It has been esteemed as a digestive and a carminative across every culture that has adopted it, from the Greek physicians and the Ayurvedic jiraka preparations to the Galenic classifications of Ibn Sina, and it is still taken across the Middle East and India as an aid to digestion, often as a simple infusion of the seeds in hot water. India today produces the overwhelming majority of the world's crop, with Unjha in Gujarat at the centre of a trade that connects Indian cumin farmers to kitchens from Lagos to London to Mexico City, and the oldest documented spice name in human history now sells, in small glass jars, on every continent.
