The Sweet & Versatile: Bell Peppers
Bell peppers are the foundational pepper for any pantry and produce no heat, registering a zero on the Scoville Heat Unit (SHU) scale. Their magic lies in their versatility and subtle sweetness. Green bell peppers, harvested earliest, have a slightly
bitter, vegetal taste perfect for slicing raw into salads or adding a refreshing crunch to stir-fries. As they ripen, they turn yellow, orange, and finally red, becoming progressively sweeter and fruitier. Red bell peppers are ideal for roasting, which concentrates their sugars, making them a fantastic addition to sauces, soups, and dips. Their sturdy structure also makes them the perfect vessel for stuffing with fillings like spiced rice, paneer, lentils, or mixed vegetables.
The Vibrant & Mild: Kashmiri Chilli
Essential in North Indian cuisine, the Kashmiri chilli is prized for its brilliant red hue and mild heat, typically measuring only 1,000-2,000 SHU. It's used less for fire and more for its unique flavour and ability to impart a stunning, natural red colour to dishes. Available as whole dried chillies or, more commonly, as a fine powder, it's the secret behind the inviting colour of restaurant dishes like vegetarian Rogan Josh, Paneer Tikka Masala, and Dum Aloo. To get the most out of it, 'bloom' the powder by sizzling it in warm oil or ghee for a few seconds at the beginning of the cooking process. This technique releases its full colour and smoky-sweet flavour into the fat, ensuring it beautifully coats every ingredient.
The Earthy & Rich: Poblano Peppers
If you're looking for a pepper with a rich, earthy flavour and just a whisper of warmth (1,000-1,500 SHU), the poblano is an excellent choice. Popular in Mexican cuisine, these large, dark green peppers have thick walls that make them ideal for roasting. Roasting enhances their smoky character and makes their skin easy to peel. Once roasted, they can be stuffed with cheese, corn, and beans for a classic 'chiles rellenos', or sliced into strips and added to creamy sauces, vegetable stews, or dal for a complex, savoury depth. When dried, the poblano becomes the ancho pepper, which has an even more concentrated, smoky taste.
The Bright & Grassy: Jalapeño Peppers
The jalapeño is one of the world's most recognizable chillies, offering a moderate and approachable heat level that ranges from 2,500 to 8,000 SHU. Its flavour is distinctly bright, crisp, and grassy when green. This makes it incredibly versatile. You can slice them raw to add a fresh, spicy kick to pizzas, tacos, and sandwiches, or mince them into fresh salsas and guacamole. Pickled jalapeños provide a tangy heat that can liven up any dish. When a mature red jalapeño is smoke-dried, it transforms into a chipotle pepper, which carries a smoky, earthy, and subtly sweet flavour perfect for marinades and sauces.
The Sharp & Fiery: Bird's Eye Chilli
Known by many names, including Thai chilli, the bird's eye chilli is small but packs significant heat, ranging from 50,000 to 100,000 SHU. Its defining characteristic is a clean, sharp, and immediate fire. In Indian cuisine, a similar variety is the Jwala chilli, which is a staple in Gujarat for its potent heat. These chillies are not just about spice; they add a distinct pungent aroma and flavour. Use them sparingly to bring a vibrant kick to Southeast Asian-inspired coconut curries, spicy stir-fries, and dipping sauces. They can be tossed in whole, sliced, or pounded into a paste to infuse a dish with their signature zest.
The Extreme & Fruity: Bhut Jolokia
Once certified as the world's hottest pepper, the Bhut Jolokia, or Ghost Pepper, from Northeast India is for the true spice adventurer. With a rating that can exceed 1 million SHU, its heat is intense and builds slowly. But beneath the fire lies a surprisingly complex and desirable flavour, often described as having smoky and fruity undertones. This is not a pepper for casual use. A tiny sliver can flavour an entire pot of food. It is traditionally used in the region to make searingly hot pickles and chutneys, or added in minute quantities to curries where it lends a unique aroma alongside its formidable heat. Always handle with extreme caution.
