How much fact do you know about peppers? Peppers, both sweet and hot, originated in Central and South America. According to U.S. Department of Agriculture records, commercial bell peppers were first produced in the southern United States in 1925.

You can flexibly use peppers in almost any food combinations, be it barbecue, baking, steaming, stir-frying with any vegetables, nuts, seeds or legumes. You can even eat them raw as snacks or in salads. It's no wonder they become the favorites of the vegetarians and vegans.

Peppers come from the colorful Capsicum family which splits into two main categories - sweet bell peppers and the spicy chilies, such as jalapenos. The difference arises from the presence of capsaicin in chilies but not in sweet bell peppers.

Sweet bell peppers are also known as capsicums, sweet peppers or green / red peppers. You can't differentiate the sweet bell peppers varieties when they're still young because they all look green. As they ripen, they'll change color. Depending on the stage of ripeness and their variety, their colors range from orange, yellow, red, purple, brown, black, ivory or green, and so do their sweetness.

But green bell peppers remain green throughout the ripening process. Thus, you may find it challenging to differentiate the other bell peppers from the green variety before they ripen.

More Facts about Peppers - Choosing Peppers

Peppers are not seasonal fruits, meaning you can find them in supermarkets any day during the year. Choose well-shaped, firm and glossy peppers which feel heavy for their size. Look out for unhealthy peppers with soft or wrinkled areas, cracks, slashes or black spots. Except for jalapeno which you'll see some tiny cracks at the end of their stems, fresh chili peppers should not have any cracks at all.

It's best to wrap the peppers in paper bags or paper towels and store in the refrigerator to keep their freshness - up to 5 days for bell peppers and up to 3 weeks for chili peppers. Remember to wash the peppers before cooking so as to remove the wax on their surfaces.
