Actually, it DOES grow on trees. It all starts with a small tropical tree, the Theobroma cacao, usually called simply, “cacao.” (Pronounced ka-KOW. Theobroma is Greek for “food of the gods.”) Cacao is native to Central and South America, but it is grown commercially throughout the tropics. About 70% of the world’s cacao is grown in Africa.
A cacao tree can produce close to two thousand pods per year. The ridged, football shaped pod, or fruit, of the cacao grows from the branches and, oddly, straight out of the trunk. The pods, which mature throughout the year, encase a sticky white pulp and about 30 or 40 seeds. The pulp is both sweet and tart; it is eaten and used in making drinks. The seeds, were you to bite into one straight out of the pod, are incredibly bitter. Not at all like the chocolate that comes from them.
It’s actually a perfect design. The fruit attracts forest animals, like monkeys, who eat the fruit but cast the seeds aside, dispersing them and allowing new trees to sprout up. (One of my favorite memories of a recent trip to Costa Rica was watching monkeys eating in a “chocolate” tree.) It’s hard to imagine why humans ever thought to do anything with the seeds.
What is it that we do with these seeds, which we call beans, to answer the question “Where does chocolate come from?” First, the pods must be harvested, which is usually done twice a year. Because the trees are too fragile to climb, harvesting is accomplished by workers on the ground, who wield either a machete or a long pole with a machete on the end. Then, workers open the pods by hand, taking care not to damage the beans inside.
Next comes one of the most important steps in the process – fermentation. The beans, still sticky with pulp, are placed in earthen pits or wooden bins and covered with banana leaves, then left to ferment. The heat of fermentation changes the bitter flavors in the beans into something more edible, more chocolatey. The sugars in the bean turn into acids, the color changes from pale to dark brown, and the pulp residue melts away. The length of the fermentation process depends on the type of bean; the higher quality beans may need only a few days, where others may need a week or more.
After fermentation, the beans are dried in the sun for about a week. The flavor continues to develop during this time. Once the beans are dry, they are ready to be shipped to a factory, where they are turned into chocolate.
