Dried Peppers: The Heat is Still On


peppers

The first thing that comes into mind when we hear the word “pepper” or “chili” is “hot and spicy” regardless if they are fresh or dried peppers.

Peppers are a large group of fruit-bearing plants and they are diverse in terms of their botanical classifications. A little complicated because black peppers are separate from the capsicums and they are not even related. And not only they are diverse, but also their pungency or spiciness are scored.

Scoville Scale

Named after its creator, Wilbur Scoville, this scale measures the spiciness of peppers and other spicy foods. It is recorded in Scoville Heat Units (SHU). It measures the concentration of capsaicin, a compound found in chili peppers.

The score ranges from 0 to over 3 million depending on the species of chili pepper. Sweet bell peppers have a score of zero SHU while the Carolina Reaper scores from 1.6 million to 2.2 million SHU. This makes the California Reaper an extremely hot pepper. It currently holds the Guinness Book of World Record since 2012.

Drying chili peppers is something common across all cultures. You may notice a difference in flavor between regular and dried peppers. Since the moisture is removed from the dried pepper, the flavor becomes intensified and the heat factor increases. In this article, we will focus only on the Capsicum group because it is here that we will encounter most of the green and red hot chili peppers we know or might have heard of.

Capsicum

Generally called the peppers, Capsicum is a genus of flowering plants under the family Solanaceae which are native to southern North America and South America. Because of world trade in early civilizations, peppers are cultivated worldwide giving rise to different cultivars and has become a key ingredient in many cuisines.

The term Capsicum may have come from the Latin word “capsa”, meaning “box” that refer to the pods. Or it may have come from the Greek work “kapto”, meaning “to gulp”. The term “pepper” comes from the similarity of spiciness to Piper nigrum, the black pepper, although they are not botanically related. The term “chili” (“chile” in Mexico) comes from the Nahuatl word “chīlli”, a large Capsicum variety that has been cultivated since 3,000 BC.

The fruit contains capsaicin (methyl-n-vanillyl nonenamide), a chemical that produces a strong burning sensation in the mouth. Capsaicin is present in large quantities in the fruit’s placental tissues which holds the seeds, on its inner membranes, and in the white pith around its seeds but not much in the seeds itself.

Different Terms

In American English, any pepper that lacks heat is known as sweet pepper and any pepper that has a block shape is known as bell pepper. Any variety that produces capsaicin is known as hot or chili pepper.

In British English, the sweet varieties are referred to as peppers and the spicy varieties are referred to as chillies.

In Australian English, capsicum refers to the bell peppers while the spicy varieties are referred to as chilli.

Nutritional Value and Usage

Peppers are highly nutritious. They contain more vitamin C and B6. Dried peppers have much different nutritional value due to dehydration and concentration of vitamins and minerals.

Peppers can be eaten raw or cooked. They can be preserved by drying, pickling, freezing, or in the form of a jam. Dried peppers may be rehydrated whole or processed into flakes or powders.

A List of Familiar Peppers

There are perhaps 50,000 Capsicum cultivars grown worldwide and there are five major species of cultivated Capsicum. Below is a list of familiar peppers we might have used and heard of.

Drying Peppers

Peppers can be dehydrated by sun-drying, air-drying, or using a home dehydrator or an oven. The finished product can be crumbled or powdered to use as a flavoring or coloring in many foods.

Soak dried peppers in water to rehydrate them for use in casseroles. Dried peppers can be stored in moisture- and vapor-proof packaging in a cool, dry, dark place for several months.

Sun-drying

Day temperatures should be higher than 85°F and humidity is around 60°F. Remove seeds, stems, and membranes before drying. Small peppers can be left whole but make a slit using a knife to speed up drying. Large peppers dry better if they are cut in half, sliced, or cut into cubes. You’ll know when peppers are completely dried when they turn brittle.

Air-drying

With a knife, make a slit on the peppers. Then using a large needle, run through a heavy thread through the stems. Hang the strings of peppers in a room where air circulates freely. High humidity may spoil the peppers before they dry. Air-drying can take 3 to 4 weeks.

Dehydrating

Dehydrator or oven temperatures should not exceed 140°F when drying peppers. Remove the seeds, stems, and membranes then slice or cut them into cubes. For small peppers, make a slit to speed up drying and dry them whole. Below is a drying guide generally for peppers.

PEPPER PREPARATION BLANCHING DRYING CHECK FOR DRYNESS
Chili peppers, green Wash. To loosen skins, cut slit in skin, then rotate over flame 6-8 minutes or scald in boiling water. Peel and split pods. Remove seeds and stem. Wear gloves if necessary. No blanching required 12-24 hours Crisp, brittle, medium green
Chili peppers, red Wash thoroughly. Slice or leave whole if small 4 minutes 12-24 hours Shrunken, dark red pods, flexible
Peppers, pimientos Wash, stem. Remove core and seeds. Cut into 1/4″ to 1/2″ strips or rings 4 minutes 8 to 12 hours Tough to brittle

Final Thoughts

With so many varieties of chili and bell peppers, it could be confusing to distinguish one from the other. But for those who love spices, this may not matter much as what we are really after is the heat that it will bring to the food.

Which of the chilis would you like to dry most of the time?
