Quinoa
Chenopodium quinoa
An Andean grain crop grown for its small, protein-rich seeds, which ripen in dense heads of white, red or black at the top of an upright annual usually 3.3 to 6.6 feet tall. Quinoa is a pseudocereal, not a grass: it belongs to the amaranth family (the goosefoot genus was formerly placed in Chenopodiaceae), is related to spinach, and shares its genus with the garden weed lambsquarters. The seeds carry a bitter saponin coat that must be soaked and rinsed off before cooking, and the young leaves are eaten cooked like spinach. A true annual sown each spring, it does best where summers are cool and may not produce seed where temperatures run too hot.

The seed is the crop, but it needs preparation first: each seed carries a coat of bitter saponins that must be removed by soaking and rinsing thoroughly until the water no longer turns soapy (Plants For A Future).
