Peppers are an essential component of Mexican cuisine with an amazing diversity of different types (Aguilar-Rincón, 2010). Figure 1 shows a list of 64 different types peppers used in Mexico and in which regions of Mexico they are most popular (Diversidad de Chiles en Mejico). In the United States, it would be useful to know which regions of Mexico the customers originate from. This would provide both a sense of the types of peppers they use in their cuisine and a sense of the markets that serve Mexican customers could supply those peppers. 

Poblanos are one of the most popular peppers in Mexican cuisine. Sometimes in the US it is called “pasilla”, which is something dried or wrinkled. When repined on the plant and then dried, the poblano pepper is called ancho.

Poblanos have a mild pungency, ranging from 1,000 to 1,5000 Scoville units.
