Sweet potato cultivation in Portugal has a long tradition. This particular variety came about in the region of Aljezur, where sweet potatoes have been raised for centuries. The soil of the Aljezur region is sandy, and the oceanic climate and the proximity of the river Mira contribute to the quality of the local sweet potato.

The pear-shaped Aljezur potato has purple or yellow-brown skin and bright yellow flesh. Its sweet flavor is reminiscent of chestnuts, and its texture is quite smooth. It is used in a wide range of recipes and products from soups and salads to traditional cakes and sweets.
