Capsicum: The Generic Name for Peppers
Capsicum is the scientific genus for a wide variety of plants in the nightshade family, Solanaceae. This genus includes both the sweet, mild peppers, like the bell pepper, and the scorching hot varieties, like jalapeños and habaneros. The naming differences arise because different English-speaking countries have adopted different common names for the non-spicy varieties.
For example, in Australia and India, people buy "capsicums" at the market, while in the UK, they are more likely to be called "peppers" or "sweet peppers". This highlights how regional dialects, rather than botanical differences, dictate the name. The American term, "bell pepper," emphasizes the distinctive shape of the cultivar, which is blocky and bell-like.
Global Names for the Mild Capsicum
- Australia & India: Capsicum
- United Kingdom: Pepper or Sweet Pepper
- United States & Canada: Bell Pepper or Sweet Pepper
- Hungary & Poland: Paprika (used for the fruit and spice)
- Spain: Pimiento Morrón
The Crucial Distinction: Bell Peppers vs. Chili Peppers
One of the most important distinctions to understand in American cuisine is the difference between a "bell pepper" and a "chili pepper". This is more than just a name; it refers to the presence or absence of capsaicin, the chemical compound responsible for a pepper's heat.
Bell peppers possess a recessive gene that eliminates capsaicin, giving them their mild, sweet flavor and a score of zero on the Scoville scale. Chili peppers, on the other hand, contain varying levels of capsaicin, resulting in a wide range of pungency. In the USA, if a recipe calls for a "pepper" without specifying, it is almost always referring to a bell pepper.
Bell Pepper vs. Chili Pepper Comparison
| Feature | Bell Pepper | Chili Pepper |
|---|---|---|
| Heat Level | None (0 SHU) | Mild to very hot (e.g., jalapeño: 2,500–8,000 SHU) |
| Capsaicin | Not present | Present in varying concentrations |
| Flavor | Sweet, crunchy, and mild | Pungent, spicy, and often smoky |
| Shape | Blocky, four-lobed, and bell-shaped | Varies widely (e.g., slender, bullet-shaped) |
| Primary Use | Salads, stuffing, frying, roasting | Sauces, seasoning, spicing up dishes |
A Rainbow of Nutrition and Flavor
Bell peppers are not only versatile in the kitchen but are also packed with essential vitamins and nutrients. Their color indicates their ripeness and affects their nutritional profile and sweetness.
- Green Bell Peppers: These are the least ripe and have a slightly more bitter, less sweet flavor than their fully ripened counterparts. They are a great source of Vitamin C.
- Red Bell Peppers: These are fully ripened green peppers, which causes their flavor to be much sweeter. They contain significantly more Vitamin A and Vitamin C than green peppers.
- Yellow and Orange Bell Peppers: These peppers are at an intermediate stage of ripeness. They are sweeter than green peppers and contain a mix of nutrients, including lutein and zeaxanthin, which are beneficial for eye health.
All colors of bell peppers are excellent sources of Vitamin C and Vitamin A, and they are also a good source of Vitamin B6, Vitamin E, and potassium. These antioxidants and nutrients contribute to overall health and immune function.
