Longhorn Peppers | Chili Type, Scoville, Flavor, Uses

What Are Longhorn Peppers?

The hot longhorn pepper is a little-known fairly spicy pepper that belongs to the Capsicum Annuum species of plants. It’s a cayenne-type pepper similar to Cow Horn Pepper (Italy) and Thunder Mountain Longhorn Pepper (China).  The origin of this pepper isn’t well recorded but believed to be from Texas, USA.

The fruits are very long (9 inches on average), much longer than a dash of typical cayenne pepper. This chili has an unusual “curl” at the end – hence the name “Longhorn”.

Today, you’ll find different varieties of longhorn chilies such as Longhorn Hybrid Pepper and Hot Longhorn Pepper which claims to be high-yielding verities.

The plant grows to 40 inches tall and will require staking due to heavy yield potential. It grows best in hot sunny climates and can be grown in containers large enough to support a tall Capsicum plant with a large volume of fruits. In ideal growing conditions, the peppers get ready for harvest in about 85 to 90 days.

How to Dry And Store Longhorn Peppers?

Medium hot peppers are great when dried and then made into chili powder. Longhorn peppers can be dried without any treatment. However, the flavor and quality of the dried chilies can be increased if you give the peppers a quick blanch before drying. Immerse the chilies in boiling water for 3-4 minutes and then quickly chill the fruits in an ice bath. You can dry the blanched peppers in whatever process you choose. Use a mesh or wire racks, or dehydrator, oven-dry, hang them, or just lay them on the mat in very arid climates.

Usually, when the peppers are cut into 1-inch pieces and split they’ll dry more quickly. In fact, it’s hard to dry large whole peppers properly without a dehydrator. Removing the seeds and ribs (inner membranes) of the pepper will reduce the heat by 50 percent or more.

By the way, blanching the chilies for 5 to 7 minutes and then chilling will peel off peppers’ skin. If you love to have the dried chilies without the skin then do it so.

Store the dried longhorn peppers in an airtight container and keep them away from humid conditions. You may also use moisture barrier plastic bags for storing the dried chili pepper. If stored well, the dried peppers will stay good for 1 to 2 years.
