There are many varieties of chiles that you'll find in grocery stores all over Arizona and the Southwest. Chiles are used often in Mexican cooking, and add a great deal of flavor, and sometimes heat, to the concoction.

A gentleman named Wilbur Scoville developed a heat index for chiles, which is the industry standard for measuring a pepper's pain to your palette. For instance, green bell peppers have a value of zero Scoville units, whereas habaneros are rated as between 200,000 and 300,000.

You'll find most of these peppers in grocery stores throughout the Valley of the Sun, but you are likely to have the largest selection at a Food City (locally owned and has a focus on Mexican and Latin American foods) or a grocery with a large produce department, like Sprouts Farmers Market. Let's begin.

First up is the serrano pepper. It is pronounced: suh-rah- noh. Serrano chile peppers have thin walls. They don't need to be steamed or peeled before using, making it the easiest chile pepper to use for salsas. The serrano chile is green in color at first and ripens to red, brown, orange, or yellow. Serrano chile peppers don't dry well since they are too meaty. It is said to be about five times hotter than the jalapeño; jalapeños are often used as substitutes for their hotter counterparts, the serrano peppers.

The serrano rates between 8,000 and 22,000 Scoville units on the heat index.

Jalapeño Peppers

The jalapeño is probably the easiest to find and the most often used at local Mexican restaurants. It is pronounced: hah-lah-pain-yo. Most people think of the jalapeño as being very hot, but it actually varies from mild to hot depending on how it was grown and how it was prepared. The heat is concentrated in the seeds and the veins, so if you want it on the milder end of its scale, remove those parts.

Jalapeños are sold canned, sliced, and pickled. Canned jalapeños may be milder than fresh because they are usually peeled and the seeds removed. Pickled jalapeños are always hot.

A chipotle (pronounced: chi-poat-lay) is a jalapeño that has been smoked. The jalapeño rates between 2,500 and 8,000 Scoville units on the heat index.

The habanero is pronounced: hah-bahn-air-oh, or, ah-bahn-air-oh, without the leading 'h' sound. You'll hear it said both ways.

The habanero is the hottest chile pepper you'll find in your local grocery stores, and they are very, very hot. The oil in the habanero, as well as many other hot chiles, can be very painful if you get it in your eyes or on open wounds on your hands. Wearing gloves while handling is your best bet.

Unripe habaneros are green, but the color at maturity varies. Common colors are orange and red, but white, brown, and pink are also seen.

Most habaneros rate 200,000 to 300,000 Scoville heat units. That's hot!!

A variety of the habanero called Red Savina used to be thought of as the hottest pepper, but it seems that now the Bhut Jolokia holds the Guinness World Record as the world's hottest spice, recording over 1,000,000 Scoville units. That's almost twice as much as the hottest habanero!
