Ube na Oka

Nigerian avocado halves with salted roasted sweetcorn, ground crayfish and palm oil

Origin: Lagos & South-East Nigeria

From the journey of Avocado.

In Nigeria, the avocado is called pear: ube oyibo ('foreign pear') in Igbo, or simply 'pear' in Nigerian Pidgin English. The renaming is not confusion but a declaration of ownership: the avocado arrived in West Africa through Portuguese and Dutch trading contact in the late eighteenth century, was absorbed into the local diet, and acquired a local identity entirely independent of its Nahuatl and Spanish origins. To a Nigerian child, pear has always been pear. The idea that it is botanically unrelated to the European pear, that it grew ten thousand miles away in Mexico for seven millennia before arriving in Lagos, is at most an interesting fact rather than a felt truth. Ube na oka (avocado with corn) is the most elemental expression of how Nigeria eats the avocado: as a street food, as an after-school snack, as a market vendor's two-item offering. Roasted corn (oka) is sold everywhere in Nigeria (on street corners, outside schools, beside bus stops), cooked over a small charcoal brazier until the kernels are blackened and caramelised on the outside while remaining starchy and sweet within. The avocado half is eaten alongside it, each bite of starchy, smoky corn followed by a scoop of cool, fatty avocado, the fat of the avocado lubricating the corn in the way that butter lubricates European bread. Ground crayfish (the dried, ground prawns that provide the deep umami bass note of much Nigerian cooking) and a drizzle of red palm oil (the foundational fat of West African cuisine, fruity and slightly earthy) complete the picture. The preparation requires almost no cooking. It requires excellent ingredients. It tastes of Lagos in the afternoon.

Ingredients

Main

  • 2 large ripe avocados (as fresh and creamy as possible)
  • 2 cobs fresh sweetcorn, husks removed

Seasoning

  • 1 tbsp ground crayfish (dried ground prawns, available in West African grocery stores)
  • 1 tbsp red palm oil (sustainable certified)
  • ½ tsp fine sea salt, plus more for the corn
  • ½ tsp ground cayenne or dried ground pepper (ose oyibo), to taste

To Serve

  • extra salt flakes, to finish

Method

  1. Roast the corn: place the corn cobs directly over the open flame of a gas hob, on a very hot ridged grill pan, or under a hot overhead grill. Turn every 2–3 minutes until the kernels are charred in patches and the corn is cooked through: about 12–15 minutes total. It should be deeply caramelised and smoky in places, not uniformly cooked. Season immediately with salt.
  2. While the corn cooks, halve the avocados and remove the stones. Drizzle the cut surface of each avocado half with a little of the palm oil. Sprinkle with ground crayfish, cayenne, and sea salt.
  3. Serve the avocado halves directly in their skins alongside the roasted corn on a plate or wrapped in newspaper in the street-food tradition. Eat by scooping avocado with a spoon alongside bites of corn, using the avocado as a fat condiment for the dry corn.

Notes

Ground crayfish is a fundamental seasoning in Igbo and Yoruba cooking, providing a deep, savoury umami that has no precise Western equivalent. It is available in Nigerian and West African grocery stores and increasingly in larger international supermarkets. If unavailable, a small amount of bonito flakes ground to a powder or a pinch of MSG approximates the umami without the oceanic character. Red palm oil is available in most African and Caribbean food stores; use sustainably sourced RSPO-certified palm oil. The preparation scales easily: at a Nigerian street stall, a full corn cob and one whole avocado constitutes a complete snack for one person.
