Cateto Orange Flint is an heirloom variety of flint corn, originally hailing from South America. Traces of its genetics are found in many commonly-grown modern varieties of maize today. Even still, this particular variety is probably the rarest variety of grain that we grow. While popularly grown in Argentina and Brazil in the late 1800s, a version of it made its way to Cuba in the early 1900s, where it became known as Maíz Argentino or Especial. Because of its relatively low soft-starch content, as well as its rich orange color, Cateto is ideal for cornmeal and polenta.
