Milagros, an 88 year old elder from Isabela, Puerto Rico, fed Sakis (our chef and herbalist) and I with her famous Arroz Con Gandules (otherwise known as rice and pigeon peas). After our fantastic meal, Milagros proudly asked us if we would like to check out the gandule plant she used to pick our gandules.
“YES!” we replied.
Gandules, cajanus cajan, also known as gandul, guandu, pigeon pea and Congo pea, is a pretty little bush with yellow flowers and green pods which hold the gandules (1).
The gandule, originally from India, was traded and planted for three thousand years in Asia and Africa (1). Currently, India grows 90% of the world's gandules for commerce (5).
SURVIVAL & NUTRIENT POWERHOUSE
Due to the horrors of colonialism, Indigenous Puerto Ricans (Taino’s) were forced onto a heavily starch-based and entrails diet to survive.
The gandule quickly became a staple because of its high nutrient density. The mighty gandule plant boasts high levels of proteins, amino acids like methionine, lysine and tryptophan (6). Believe it or not, there is even a preliminary report on the cure of nutritional anemia with gandules (3).
