Chile or Chili? Spelling doesn’t Matter – Scoville Units Do

mexican restaurant san diegoEveryone who seeks a fine meal in any Mexican restaurant San Diego knows Mexican cuisine depends on chile peppers for their zest and spirit but not everyone realizes there are a wide variety of peppers that answer to the name of chile, or is it chili? Even the spelling is open to question.

The Nahuatl, or Aztecs, preferred chili but the Spanish when they discovered the amazing pepper spelled it chile. While this building block of Mexican cuisine was new to Spaniards, the Mayans had been boiling them with beans and mixing them with cacao since 7500 BC. The Mayans may have been engaging in the first form of organic gardening, or perhaps it was just a coincidence that they planted the hot peppers alongside tomatoes but the end result was that, the capsaicin, responsible for the burning effect of chile peppers, served as a mammal repellent, allowing the tomatoes to thrive, with minimal destruction of the pepper crop.
Hot Facts

The hotness of any variety is dictated by the amount of a compound called capsaicin inherent in it.Their heat index is measured in Scoville units, and is expressed as a range since heat intensity can vary from pepper to pepper.

The best way to get a feel for Scoville units is to look at some of the most popular peppers in light of the Mexican dishes they flavor.
