Conkies are made all over Barbados in late November for Independence Day on 30 November, when they're sold at roadside stalls and steamed in big pots at home; older Bajans remember them from Guy Fawkes Night, too. A spiced batter of grated pumpkin, sweet potato and coconut, cornmeal, sugar and raisins is folded into squares of banana leaf and steamed until it sets. Unwrapped, they're moist, dense, sweet and fragrant with nutmeg, almond and the faint green tea scent of the leaf. Chef's tip: pass the banana leaves briefly over a gas flame or dip them in hot water first; they turn glossy and supple and fold without splitting.
