There is an improperly used word in the well-written and awfully interesting article about chilis at Yale University.
“But trade in spices did not wet the North American palate for hot chili peppers.”
The author obviously meant, “whet the North American palate” – as in, sharpen it. Introducing liquid to a palate [“wetting it”] won’t create a further desire in that palate for a certain food taste.
According to the article, chilis were disseminated from South America and made their way from there around the world to Asia, India and other countries. The capsaicin chilis contain is excellent for treating a variety of physical ills such as swollen feet and varicose veins, and it also creates a sense of well-being in those whom eat it.
