Vegetables - Capsicum : Introduction

Capsicum is a genus of plants from the nightshade family (Solanaceae). Some of the members of Capsicum are used as spices, vegetables, and medicines. The fruit of Capsicum plants is commonly known as chile pepper or just pepper.

They originated in Central and South America, but are now grown worldwide.

Capsaicin

The fruit of most species of Capsicum contains capsaicin (methyl vanillyl nonenamide), a lipophilic chemical that can produce a strong burning sensation in the mouth (and, if not properly digested, anus) of the unaccustomed eater. Most mammals find this unpleasant; however birds are unaffected, and it therefore appears that the secretion of capsaicin is an adaptation to protect the fruit from consumption by mammals while the bright colors attract birds that will spread the seeds. The amount of capsaicin in peppers is highly variable and is dependent on genetics, giving almost all types of peppers varied amounts of perceived heat. The only pepper without capsaicin is the bell pepper. Chile peppers are of great importance in Native American medicine, and capsaicin is used in modern Western medicine—mainly in topical preparations—as a circulatory stimulant and pain reliever.

Cuisine

Capsicum fruits and peppers can be eaten raw or cooked. Those used in cooking are generally varieties of the C. annuum and C. frutescens species, though a few others are used as well. They are suitable for stuffing with fillings such as cheese, meat or rice.

They are also frequently used both chopped and raw in salads, or cooked in stir-fries or other mixed dishes. They can be sliced vertically and fried, or chopped and incorporated into salsas or other sauces.

They can be preserved by drying or pickling. Dried peppers may be reconstituted whole, or processed into flakes or powders. Pickled or marinated peppers are frequently added to sandwiches or salads. Extracts can be made and incorporated into hot sauces.

In 2005, a poll of 2,000 people revealed the capsicum pepper to be Britain's 4th favourite culinary vegetable.
