Let’s deep dive into the world of peppers to find out the best way to use them so you can take any bland meal to a dynamic flavor explosion.

Pepper Facts and Origin Story

Most people think peppers are brightly colored vegetables, but did you know that they aren’t even technically veggies?

Botanically, peppers are considered fruits, although they are often called vegetables in the culinary world.

Chili peppers are classified as nightshades or members of the Solanaceae family, which is linked to cherries, tomatoes, and eggplants.

Peppers can come in dull colors too, like brown, or stray from their typical spiciness and be anything from sweet to citrusy to earthy.

The short version of their origin story is that they were only ever grown in Latin America until the Spanish and Portuguese arrived and exported them in large numbers, alongside other crops, to the rest of the world.

Scoville Heat Unit Scale

Peppers have varying heat levels that can be measured using a Scoville Heat Unit (SHU) scale. The scale ranges from 0 to as high as 5 million and gives you a good idea of the variety of spice levels in the pepper family. All spicy peppers are this way because of the capsaicin present in the plant membrane.

Why Are Peppers Different Colors?

Peppers typically start out green, although a couple of varieties are purple when budding; these colors result from the presence of chlorophyll in the young fruit.

As they mature, the chlorophyll dissipates, and other organic pigments, like lycopene, take their place, making the peppers bright red.

Certain carotenoids are also responsible for the colors of some pepper varieties; they typically make them yellow or orange.

Chlorophyll, anthocyanins, and carotenoids are generally responsible for the different colors of peppers.

How Many Types of Peppers Are There?

Peppers are from the genus Capsicum and are estimated to have 50,000 varieties. I’ll touch on some of the most popular varieties available in the U.S.

Bell Peppers

Bell peppers are the most common and least spicy pepper variety on the market. These sweet and mildly flavored crops come in the following colors: red, orange, green, yellow, purple, brown, white, candy cane, and striped.

Brightly colored bell peppers, like the red and orange varieties, tend to be quite sweet, while the tepid colored varieties, like the green bell peppers, taste leafy and slightly bitter.

Bell peppers add crunch, color, and a distinctly sweet flavor to meals. They can be used to make salads, fajitas, stir-fries, or creamy soups.

You can also snack on them alone or with dips like hummus or make them into yummy appetizers by stuffing them with fillings.

Other Names: Sweet bell peppers, red pepper, and green bell peppers

Origin: Mexico and South and Central America

Heat Level: 0 Scoville Heat Units (SHU)

Ghost Peppers

The ghost pepper, also known as bhut jolokia, is the former Guinness World Record Holder for the hottest pepper in the world.

These spicy peppers are typically red but can also be yellow or orange. A fun fact about these peppers is that they’re used to make high-grade military smoke bombs in India, where they originate.

These peppers present interesting and varying flavors that unfurl when put through cooking processes like slicing, pounding, and fermenting.

Ghost peppers are great for ghost pepper hot sauce, spicy chutney, and curry.

Jalapeño Peppers

Jalapeños have a leafy flavor similar to that of green bell peppers; however, they provide far more spice than their bell-shaped counterparts.

Just like green bell peppers, jalapeños are typically harvested unripe or while they’re still green on the vine, which may contribute to the earthy flavor. When grown to maturity, jalapeños take on a red shade and taste mildly fruity and sweet.

Dried and smoked jalapeños are called chipotles and have two varieties: meco and moritas. Meco chipotles are moderately spicy, while moritas are super hot.

The jalapeño pepper or chipotle is commonly used in a number of dishes, including salsa, vegan chilis, soups, escabeche, adobo, and other fun dishes.

Other Names: Chipotle

Origin: Mexico

Anaheim Peppers

If canned green chili peppers are one of your go-to kitchen staples, Anaheim peppers, named after the second largest city in Orange County, might just make up a significant part of your diet.

Anaheim peppers have a tangy, smoky, and mildly spicy flavor that stands out in dishes but not in an intense way that overshadows other ingredients.

These peppers are often used commercially to make canned foods and are a mainstay of many southwestern cuisines.

The fully ripe and deep red versions of these peppers are called California red chiles or chile colorado. A hotter strain of these peppers grown in New Mexico is called hatch chiles.

These peppers can be used to make marinades, salsas, mole sauces, chile relleno, stews, and more.

Carolina Reaper

Carolina Reapers are the second-hottest peppers in the world, and they’re quite hard to find (probably for your own good!). Don’t eat these peppers raw or handle them with your bare hands.

Ingesting a mouthful of pepper spray might be a close experience to eating a Carolina reaper since pepper spray measures about 5 million on the Scoville scale, while Carolina reapers are about 2 million–hotter than almost any other pepper.

These peppers have a wrinkly exterior and a sometimes pointy and small tail that extends inwards. Using Carolina Reapers to make hot sauce, flakes, powders, and hot wings isn’t too bad if you can handle their extreme heat levels and use them in moderation.
