Bird’s eye chili, bird eye chili, bird’s chili or Thai chili is a chili pepper, a variety from the species Capsicum annuum, commonly found in Ethiopia and across Southeast Asia. It is often confused with a similar-looking chili derived from the species Capsicum frutescens, the cultivar siling labuyo. Bird’s eye chiles are small, thin, pointy peppers that are red when mature.
They are green when unripe but can still be eaten, and are sometimes orange or purple depending on maturity.The bird’s eye chili is small, but is quite hot (piquant). It measures around 50,000 – 100,000 Scoville units, which is at the lower half of the range for the hotter habanero, but still much hotter than a common jalapeño.
