Origin of vanilla
Vanilla is native to the American rainforest and specifically from Mexico. The ancient Aztecs knew it as Txilotxitl or Tlilxochitl, meaning “black flower”.
Spanish colonists imported the aromatic spice to Europe. Numerous spice trade routes for centuries have made this spice to be cultivated in many other places, such as Africa and tropical Asia.
Currently, vanilla has become one of the most commercial scents, being applied in cosmetics (perfumes, creams, shampoos, gels,…) and especially in the food industry, forming one of the favorite flavors for chocolate, sugary drinks, cakes, pastries, etc.
What is vanilla flavor?
The scent of vanilla is sweet and intensely aromatic, typically used as a spice for sweet preparations. Its aroma is due to a phenol it contains, called vanillin.
There are varieties of African and Mexican vanillas. Although the plant is native to Mexico, the African variety is now more appreciated because it has a more intense flavor, with bitter aftertaste, as well as being more economical.
Paradoxically, in the “gourmet” Mexican shops, people is shopping Bourbon vanilla (the African variety), instead of commercializing the local vanilla which grows in this country, that would be greener and authentic
Whatever variety it may be, the good vanilla has crystals on the outside of the pod, which correspond to vanillin when crystallized.
