Bolo de alfarroba

Carob and orange cake

Carob trees grow all through the dry Barrocal hills behind the Algarve coast, and the toasted pods are ground into a sweet, cocoa-coloured flour that local bakers have used for generations. This cake, sold by the slice in cafés around Loulé and São Brás de Alportel, is made with olive oil and orange, so it stays moist for days. It has a gentle caramel, almost malty taste rather than a chocolate one. A common mistake is using too much carob; it is sweet and earthy and turns bitter when overdone, so stick to the amount given. Chef's tip: sieve the carob flour with the wheat flour, because it lumps easily and leaves dry pockets in the crumb.
