Calathea allouia

In appearance and culinary use, it is similar to potatoes. But the use of this tuberous root native to tropical America is restricted to the Amazon region, where it is a staple for native Indians and riverside communities. Occasionally, it can be found in farm markets of bigger cities such as Belém, Manaus, Parintins and Santarém. The sweet taste − for some, reminiscent of corn, or Brazil nut − and the crunchy texture it acquires after cooked goes well in salads, stews, soups, mashes and gratins.
