Origin

Clarence Brown Hamlin cultivated Fresno peppers [1] in 1952. He named the peppers after Fresno, California.

Compared with Jalapeno

The Fresno pepper looks surprisingly like jalapeno and comes in red and green. In addition to looks, it tastes similar as well.

The Fresno pepper tastes vegetable-like when green, identical to the jalapeno. However, after maturing, it has a fruiter, smokier taste than its famous relative.

SHU

It ranks slightly higher on the Scoville charts, with a heat unit rated between 2,500 to 10,000. As a result, it has a spicier heat compared to jalapeno.

Its spiciness increases with age, so if you’re a spice head, it doesn’t hurt to let your Fresno peppers mature.

Usage

Fresno peppers are particularly popular in dishes such as ceviche and salsa. They also make excellent sides to pair with rice.

What Is Jalapeño?

Origin

Jalapenos originated in Jalapa (also spelled Xalapa) in Mexico. In Mexico, jalapenos are grown [2] across almost 40,000 acres of land in three agricultural zones.

Meanwhile, in the United States, roughly 6,000 acres of land are dedicated to farming this pepper. Most jalapenos cultivated in the United States are grown in Texas and New Mexico.

Colors

Jalapenos come in green and red. The red jalapeno is a mature pepper. Red jalapenos received more time to grow than their green counterpart. The green pepper has a very crisp, earthy smell and taste.

On the other hand, mature red jalapenos have a light sweetness to them. For reference, the famous hot sauce Sriracha uses red jalapenos for its base.

Usage

You can enjoy Jalapeno peppers in a variety of ways. They are often used in hot sauces and salsas, as well as breaded or stuffed and deep-fried. Because of their light kick, they are sometimes used in salads to provide an extra dimension of flavor.

Perhaps one of the most important uses for the jalapeno pepper is its use in the production of Chipotle pepper. In this process, ripe red jalapenos are smoked and dried.

Pecan wood is traditionally used to smoke jalapeno peppers, but it can be substituted for other woods. Great options for wood substitutes include oak, cherry, and hickory.

As a side note, smoking your jalapeno peppers increases their antioxidant capacity [3].

Differences in Appearance

The Fresno pepper has thinner walls than the jalapeno. They are a beautiful glossy red when they are fully grown. They typically grow to two inches long, with three being the maximum.

On the other hand, although jalapenos are also red when matured, they are best harvested at around eight weeks old. At that time, the pepper is a gorgeous glossy dark green. They’re firm and roughly three inches long. At its largest, a jalapeno can be up to 6 inches long.

Despite the disparity in size, for their most common uses, jalapenos are smaller than the Fresno pepper. Although Fresno peppers are thinner than jalapenos, they still cannot be swapped at a 1:1 ratio.

Differences in Taste

As mentioned earlier, the Fresno pepper has a richer taste when it’s allowed to mature. It’s fruitier, richer, and is wonderful for use in sauces.

A mature jalapeno pepper is sweeter than when it’s green. It does not have the rich smokey flavor of the Fresno pepper.

Pepper spiciness is rated by Scoville units. The creator of the Scoville scale [4] is Wilbur Scoville, an American pharmacist. The Scoville scale measures the pungency or heat of a pepper based on the concentration of capsaicinoids. The measurement is then recorded in Scoville Heat Units.

Whether you prefer red or green peppers, the Fresno pepper, and the jalapeno share a list of similarities and differences that make eating them exciting.

Are you a fan of earthy vegetable flavors? You can choose between either the jalapeno or the Fresno pepper. If you prefer a deeper, fruity flavor, then mature Fresno pepper is for you.
