Small chili, known for its intense heat and vibrant flavor, is an essential ingredient in Vietnamese cuisine and many other culinary traditions. These small, fiery chilies, which belong to the genus Capsicum, are prized for their heat, aroma, and nutritional value. There are several varieties of small chili, but the two most commonly cultivated in Vietnam are Capsicum frutescens and Capsicum annuum, often referred to as bird’s eye chili and Thai chili respectively.
1. Scientific Classification and Varieties
Small chilies are part of the Solanaceae family (nightshade), which includes other crops like tomatoes, potatoes, and eggplants. While both Capsicum frutescens and Capsicum annuum are cultivated for export and local consumption, they differ slightly in appearance, heat, and growth characteristics.
| Scientific Name | Capsicum frutescens | Capsicum annuum |
| Common Name | Bird’s Eye Chili (Ớt hiểm) | Thai Chili (Ớt chỉ thiên) |
| Heat Level | 50,000 – 100,000 Scoville units | 30,000 – 50,000 Scoville units |
| Size | 2-4 cm in length | 4-7 cm in length |
| Color | Green (unripe), Red (ripe) | Green (unripe), Red (ripe) |
| Flavor | Intensely spicy, slightly smoky | Spicy with mild sweetness |
| Uses | Spicy sauces, curries, pickles | Garnishes, stir-fries, dipping sauces |
Both varieties are rich in capsaicin, the compound responsible for their heat and anti-inflammatory properties.
