The Method
1
Remove all skins from the dried black-eyed peas by rubbing them between the palms and rinsing repeatedly in cold water. Soak the naked peas in cold water for 30 minutes, drain, then soak again in fresh cold water for a further 30 minutes. Drain thoroughly. The peas should be uniformly cream-coloured, with no trace of skin remaining — any skin left will produce a bitter, dense result.
2
Transfer the soaked peas to a food processor or stone grinder with the chopped onion and the ground dried shrimp. Process to a smooth, thick paste. Transfer to a bowl and beat vigorously with a wooden spoon or by hand for at least five minutes, incorporating as much air as possible. The paste is ready when it is noticeably paler, holds a soft peak, and a small amount dropped into cold water floats — this aeration is what produces the light, hollow interior that defines acarajé.
3
Season the paste with salt. Heat the dendê palm oil in a deep, heavy pan to 175°C. This step is where the dish lives or dies: below 175°C the acarajé absorbs oil and is greasy; above 175°C the exterior carbonises before the interior is cooked through. Use a probe thermometer and maintain the temperature throughout frying.
4
Shape the paste into rough ovals of approximately 60–70 g each using two wet spoons. Lower gently into the dendê oil in batches of two or three. Fry, turning once, until the exterior is deep golden-amber and the surface is set and lightly crisp. The interior should be soft and fully cooked through. Remove with a slotted spoon and drain briefly.
5
Prepare the vatapá: combine the ground dried shrimp, ground peanuts, and coconut milk in a small pan over medium heat. Stir continuously, adding the dendê palm oil, until the mixture thickens to a paste stiff enough to be scooped with a spoon and hold its shape — it must not be runny, or it will immediately soak through the acarajé.
6
Prepare the caruru: cook the sliced okra with the dried shrimp in a small pan over medium heat, stirring, until the okra is tender and the mixture has thickened to a cohesive stew. The colour will darken slightly and the mixture will no longer appear watery.
7
Split each hot acarajé along one side without cutting all the way through. Fill immediately with a spoonful of vatapá, a spoonful of caruru, a pinch of salted dried shrimp, and sliced or whole pimenta according to preference. Serve at once — acarajé must be filled and eaten immediately; the contrast of the hot, crisp exterior with the warm filling is essential and cannot be recovered once the shell cools.
