Bird's eye chillies are small, pointed, very hot chillies used across Southeast Asia and Africa. The name covers several varieties of Capsicum annuum and Capsicum frutescens.
What it is¶
"Bird's eye" is a trade name rather than a single variety: it covers small, pointed chillies 2–4 cm long, usually borne upright on the plant, green ripening to red, and much hotter than their size suggests, typically around 50,000–100,000 SHU. Most Thai bird's eye chillies, prik kee noo ("mouse-dropping chilli"), are Capsicum annuum. The African bird's eye, also called piri piri, and some Southeast Asian strains are Capsicum frutescens, the species of the Tabasco pepper. In the market, you are unlikely to be told which.
The name is usually explained by the pod's resemblance to a bird's eye, or by the fact that birds eat the fruit and spread the seeds; birds lack the receptor that makes capsaicin burn, so they feel no heat.
Origins and history¶
Chillies reached Southeast Asia in the sixteenth century, largely through Portuguese traders working from Goa and Malacca, and were adopted remarkably quickly into cuisines that already relied on pungent ingredients such as black pepper, galangal and ginger. Small, hot chillies suited the climate, grew almost wild in gardens, and dried easily. By the time European observers described Thai cooking in detail, chilli was indispensable. Today Thailand and Vietnam grow and eat enormous quantities, and bird's eye chillies are the everyday hot chilli from Indonesia to the Philippines.
Flavour and aroma¶
The flavour is mainly heat: sharp, immediate and clean, with a grassy note in green chillies and light fruitiness in red. The burn hits the front of the mouth quickly and fades faster than a habanero's. Because the pods are tiny and thin-walled, most of the chilli is skin, seed and placenta, which concentrates the capsaicin.
In the kitchen¶
Bird's eyes are used whole, chopped, pounded and dried.
- Thai cooking: pounded with garlic and lime for som tam (green papaya salad); in green curry paste; chopped into nam pla prik (fish sauce with chilli and lime), the condiment on every Thai table. See thai cuisine.
- Vietnamese: sliced into nước chấm dipping sauce and served on the side with phở.
- Malaysian and Indonesian: pounded into sambal and chilli pastes.
- Stir-fries: bruised whole chillies in pad kra pao (holy basil stir-fry) with holy basil and garlic.
- Dried: toasted and ground into Thai roasted chilli powder, used on noodle soups and larb.
As a guide, one to three bird's eyes flavours a stir-fry for two with real heat; Thai cooks may use ten or more. Bruise them with the flat of a knife rather than chopping to release heat more gently.
💡 Nam pla prik
Slice 4–5 bird's eye chillies thinly, add 1 small clove of garlic, sliced, 4 tbsp fish sauce and the juice of 1 lime. Leave 10 minutes. Spoon over rice, eggs and stir-fries.
Buying and storing¶
Bird's eye chillies are sold loose or in small packs in Asian grocers and most supermarkets. Choose bright, firm pods. They keep in the fridge for one to two weeks and freeze exceptionally well: freeze a whole bag and take out a few at a time. They also air-dry easily on the stalk in a warm room.
Substitutes¶
- Piri piri: the African bird's eye, essentially interchangeable.
- Serrano: milder and fleshier; use two or three per bird's eye.
- Dried chile de árbol or chilli flakes in cooked dishes.
- Cayenne for heat in a pinch.
Pairs well with¶
Garlic, lime, fish sauce, palm sugar, lemongrass, galangal, makrut lime leaves, thai basil, coriander leaf, shallots, coconut milk and pork.
Growing your own¶
Bird's eye types are compact, bushy and very productive, ideal for pots on a sunny windowsill or greenhouse shelf. Sow indoors in February–March at 20–25°C. Plants stay 30–60 cm tall and carry dozens or hundreds of upright pods. They will crop outdoors in a warm, sheltered British summer but do better under cover. Pick green or red; both are hot.
