About
Synsepalum dulcificum is a plant in the Sapotaceae family, native to tropical Africa. It is known for its berry that, when eaten, causes sour foods (such as lemons and limes) subsequently consumed to taste sweet. Common names for this species and its berry include miracle fruit, miracle berry, miraculous berry, sweet berry, and in West Africa, where the species originates, àgbáyun (in Yoruba), taami, asaa, and ledidi.
The berry itself has a low sugar content and a mildly sweet tang. It contains a glycoprotein molecule, with some trailing carbohydrate chains, called miraculin. When the fleshy part of the fruit is eaten, this molecule binds to the tongue's taste buds, causing sour foods to taste sweet.
How to grow it
The plant grows best in soils with a pH as low as 4.5 to 5.8, in an environment free from frost and in partial shade with high humidity. It is tolerant of drought, full sunshine, and slopes.
The seeds need 14 to 21 days to germinate. A spacing of 4 m (13 ft) between plants is suggested.
Uses
In tropical West Africa, where this species originates, the fruit pulp is used to sweeten palm wine. Historically, it was also used to improve the flavor of soured cornbread, but has been used as a sweetener and flavoring agent for diverse beverages and foods, such as beer, cocktails, vinegar, and pickles.
