Kunun gyada (groundnut and rice gruel)

Breakfast sellers in Kano and Zaria pour kunun gyada from big flasks into bowls, steaming hot on cool mornings and at Ramadan suhoor. Raw groundnuts are blended into a milk, boiled with rice until it thickens, and then soured with tamarind, which gives a creamy, nutty, sweet-sour gruel with soft grains of rice. It is filling enough to stand as breakfast on its own, or with a few pieces of kosai. Groundnut milk foams up just like dairy milk and is the cause of the most common mishap, so use a big pan and stay close. A frequent slip is adding the tamarind too early, which can make the groundnut milk curdle; stir it in at the end. Chef's tip: add the tamarind off the heat; boiling it hard can make the gruel split grainily.
