Carob - the Algarve's Chocolate

Food & Drink

Carob is one of the Algarve's most ancient and undervalued crops, a tree that has shaped the landscape and local economy for centuries yet remains largely unknown to visitors who pass beneath its canopy without recognition. The carob tree, Ceratonia siliqua, is an evergreen with glossy dark leaves and thick, twisted trunks that can live for hundreds of years. Its fruit, a long brown pod that ripens in autumn, has been used as food, animal feed and an industrial raw material since antiquity, and in the Algarve it has recently found a new role as a local alternative to chocolate.

The carob tree is superbly adapted to the Algarve's climate. It thrives on poor, rocky soils, requires no irrigation once established, and tolerates the intense summer heat that stresses many other crops. Carob groves are found throughout the barrocal zone, the limestone hills between the coast and the mountains, often growing alongside almond and olive trees in a traditional agroforestry system that has been practised for generations. The trees require virtually no chemical inputs, making carob an inherently sustainable crop.

Carob pods are harvested between September and November by shaking or beating the branches with long poles, a process that has changed little over the centuries. The pods fall to nets spread on the ground beneath the trees and are collected and dried. Inside each pod, hard, uniform seeds are embedded in a sweet, brown pulp. The seeds, remarkably consistent in weight at around 200 milligrams each, are the origin of the carat, the unit of measurement used for gemstones and precious metals. In antiquity, jewellers used carob seeds as a reference weight because of their natural uniformity.

The pulp of the carob pod is naturally sweet, with a flavour that genuinely resembles chocolate, though milder and without the bitterness. When dried and ground into powder, carob can be used as a direct substitute for cocoa in many recipes. It contains no caffeine and no theobromine, the stimulant compounds found in chocolate, making it suitable for those who are sensitive to these substances. It is also naturally lower in fat than cocoa and contains no oxalic acid, which can interfere with calcium absorption.

In the Algarve, carob has been transformed into a range of food products that capitalise on its chocolate-like qualities. Carob flour is used in cakes, biscuits and confectionery, and several local producers make carob bars and pralines that are sold in health food shops and tourist outlets. Carob syrup, a thick, dark liquid produced by boiling and concentrating carob pod extract, is used as a natural sweetener and as a topping for pancakes, yoghurt and ice cream. Carob liqueur, combining carob extract with alcohol, is a popular souvenir.

Beyond food, the carob seed produces locust bean gum (E410), a thickening and stabilising agent used extensively in the food industry. This industrial application has historically been the main economic driver for carob cultivation in the Algarve, and Portugal is one of the world's largest producers of locust bean gum. The gum is extracted from the seed endosperm and is used in ice cream, yoghurt, cheese, bakery products and numerous other processed foods. A carob processing factory in Faro handles much of the Algarve's crop.

The carob industry in the Algarve went through a period of decline in the late twentieth century, as rural depopulation and the growth of tourism led to the abandonment of many groves. Trees were felled to make way for development, and younger generations showed little interest in the labour-intensive harvest. However, the growing demand for plant-based, gluten-free and caffeine-free foods has revived interest in carob, and several small producers are now cultivating and marketing carob products as premium, artisanal goods.

Visitors can encounter carob culture at several points across the Algarve. The Loule market sells carob products including flour, syrup and sweets. The Alfarrobeira café concept, using carob as a centrepiece ingredient, has appeared in several Algarvian towns. And simply walking through the barrocal countryside in autumn, when the fallen pods crunch underfoot and their sweet, slightly fermented scent fills the air, provides an evocative connection to one of the region's oldest agricultural traditions.
