Red Hot Chili Peppers are more than just a band, they’re a vegetable. While we’re talking about red hot chili peppers, we might as well discuss the 50,000 other kinds of peppers. Besides a vast array of colors and shapes, there’s another reward from peppers: They’re delicious. Let’s narrow it down to a few of our farmers market favorites. Sweet bell peppers go well with nearly anything and everything. They also taste great on their own. Hot pepper varieties spice up many recipes. Some peppers add color and flavor. For example, pimiento pepper in stuffed olives or deviled eggs with paprika dusted on top. (Paprika is made from dried peppers.) Stuffed peppers, pickled peppers, fried peppers — with so many varieties, they fit in deliciously everywhere.
History of Peppers
Prehistoric remains in Peru show where peppers may have first existed. They were cultivated in Central and South America in early times. Columbus brought them to Europe in 1493, and they were quickly adopted and cultivated. Up til then, the Europeans only knew the black-and-white spice we sprinkle out of pepper shakers. It was the Europeans that gave peppers their name. When Columbus brought dried peppers back from the West Indies, Europeans said the fruit was “hotter than the pepper of the Caucasus,” the familiar table spice. The name “pepper” stuck, and we’ve used it ever since.
Despite sharing the same name, table pepper and the sweet and hot peppers we grow are not related. Table pepper is ground from the seeds of a plant called Piper nigrum. Meanwhile, most garden peppers are from the Capsicum annuum family. This group accounts for most of the varieties grown in the United States. Exceptions include the Tabasco and Habanero peppers, which are separate species.
Peppers, the plentiful
With more than 50,000 peppers ranging, we can only cover a few of them. One of the easiest ways to categorize peppers is by thinking of their capsaicin level. Capsaicin is what gives peppers their heat. It ranges from mild to spicy.
For this, we’ll use the Scoville heat unit scale. Created by an American pharmacist, Wilbur Scoville, the Scoville scale measures the pungency of peppers based on the concentration of capsaicinoids, among which capsaicin is the main component.

What to look for when buying peppers
Look for peppers that are firm and heavy for their size. The color should be vibrant. Avoid peppers with shriveled or soft spots. That usually means spoilage or mishandling has occurred. The stems should look fresh, not shriveled or dry. Dried peppers should smell fragrant when rubbed with your fingers. This indicates the essential oils are still fresh. Spice powders should be bright with color, never dull.
Storing peppers
You can store peppers in a plastic bag for up to a week. Wash them only before use, and do not wash before you store them. This decreases humidity and prevents rotting. Store cut peppers in an airtight container for one to two days.
That’s a lot of peppers!
