Habanero peppers first originated in Amazonia Brazil before spreading north into Mexico and the Caribbean, where they are used in local dishes and sauces today. The fruits mature from green to their final white colour at maturity and are typically 1.5cm and 2cm long. The fruit walls are quite thin and have a fruity/citrus almost aromatic flavour although devilishly hot, with up to 350,000 SHU (Scoville units).
