Discover six steps to hotter chillies.

A chilli’s heat is measured on the Scoville scale, a test created in 1912, in which the more water needed to dilute a chilli solution before a human taster can no longer detect the chilli determines the number of Scovilles. Today, testing is done by machines, but the measure is the same. A score of around 3,000 Scovilles is deemed hot, with record-breaking chillies topping the million mark.

The very hottest varieties are slow growing and need heat and humidity, so are best grown indoors.

Here are eight super-hot chillies to grow.

The hottest part of a chilli

The hottest part of the chilli is the placenta – the white, pithy strip that attaches the seeds to the pod. So if you want to reduce the heat before cooking, remove both the seeds and the placenta. The tip of the fruit, furthest from the stalk, is usually the mildest bit.
