Gofio is a sort of Canarian flour made from roasted grains or other starchy plants, some varieties containing a little added salt. Gofio has been an important ingredient in Canarian cooking for some time, and Canarian emigrants have spread its use to the Caribbean and the Western Sahara. There are various ways to use it, such as kneading, dissolving in soup, and baking. It can also be used as a thickener. It is also found in Argentina, Uruguay, and Chile, where it is known as harina tostada and is employed in a wide variety of recipes. The gofio commercially available in the Canary Islands is always finely ground, like ordinary flour, despite the definition given in the Spanish Dictionary of the Royal Academy.

The ferns are a group of vascular plants that reproduce via spores and have neither seeds nor flowers. They differ from mosses by being vascular, i.e., having specialized tissues that conduct water and nutrients and in having life cycles in which the branched sporophyte is the dominant phase.
