Peppers are one of the most colorful, flavorful, and versatile ingredients in the kitchen. From sweet bell peppers to fiery chili peppers, they appear in cuisines all over the world and bring everything from mild sweetness to intense heat. Whether eaten raw, roasted, grilled, or dried, peppers add depth, aroma, and visual appeal to countless dishes.
What Are Peppers?
Peppers belong to the Capsicum family and are technically fruits, although they’re used like vegetables in cooking. They originated in Central and South America and spread worldwide after the 15th century, becoming a cornerstone of many national cuisines.
Peppers are broadly divided into:
- Sweet peppers (no heat)
- Chili peppers (mild to extremely hot)
Sweet Peppers Explained
Bell Peppers
Bell peppers are the most common sweet pepper variety. They have thick flesh, a crisp bite, and a mild, slightly sweet flavor.
Colors and flavor differences:
- Green: Harvested early, slightly bitter and grassy
- Yellow & Orange: Sweeter and fruitier
- Red: Fully ripe, the sweetest and richest in nutrients
Bell peppers are ideal for salads, stir-fries, roasting, stuffing, and sauces.
Other Sweet Peppers
- Pointed peppers (Ramiro-type): Sweet, thin-skinned, perfect for roasting
- Padrón peppers: Mild overall, but occasionally spicy
- Cubanelle peppers: Popular in Mediterranean and Latin cooking
Chili Peppers and Heat Levels
Chili peppers range from gently warm to intensely hot. Their heat comes from capsaicin, a natural compound concentrated in the seeds and inner membranes.
The Scoville Scale
Heat is measured in Scoville Heat Units (SHU):
- Bell pepper: 0 SHU
- Jalapeño: 2,500–8,000 SHU
- Serrano: 10,000–25,000 SHU
- Cayenne: 30,000–50,000 SHU
- Habanero: 100,000–350,000 SHU
- Ghost pepper & Carolina Reaper: Extreme heat
Popular Chili Varieties
- Jalapeño: Mild heat, fresh and grassy
- Serrano: Sharper heat, great for salsas
- Cayenne: Bright heat, often dried and powdered
- Habanero: Fruity but very spicy
- Chipotle: Smoked jalapeño with deep flavor
Health Benefits of Peppers
Peppers are not just flavorful—they’re extremely nutritious:
- High in vitamin C, especially red bell peppers
- Rich in vitamin A (from beta-carotene)
- Contain antioxidants that support immune health
- Low in calories and high in water content
- Chili peppers may boost metabolism and circulation
Capsaicin is also linked to anti-inflammatory properties and appetite regulation.
How to Buy Fresh Peppers
Choose peppers that are:
- Firm and glossy
- Heavy for their size
- Free from wrinkles or soft spots
- Brightly colored (for ripe peppers)
Avoid peppers with dull skin or signs of mold near the stem.
How to Store Peppers Properly
- Store fresh peppers in the refrigerator
- Keep them dry in a breathable bag
- Sweet peppers last about 1–2 weeks
- Chili peppers keep slightly longer
Cut peppers should be sealed and used within 2–3 days.
Cooking with Peppers: Essential Tips
- Remove seeds and membranes to reduce heat
- Use gloves when handling hot chili peppers
- Cooking mellows heat and enhances sweetness
- Roasting intensifies flavor and adds smokiness
Peppers pair beautifully with garlic, onions, tomatoes, olive oil, herbs, cheese, meat, fish, and grains.
