The chilli – a small pepper that packs a lot of punch. This fiery ingredient is popular all over the world and is versatile enough to feature in dishes of virtually every cuisine on the globe. But what makes them so hot – literally and figuratively? Read on to find out…

Is it getting hot in here?

If you like chillies you’re not alone – they have been part of the human diet since at least 7500 BC. Though they originated in the Americas through trade, chillies eventually spread all over the world and became popular in Europe as a substitute to peppercorn, which at the time was very costly. Today, India is the largest producer, consumer and exporter of chillies anywhere and among the most popular varieties are the bell pepper, Jalapeno and Habanero.

Not all Chillies are created equal – some are hot, while some are very hot. You can tell the difference using the Scoville scale, which measures the pungency of chili peppers – the higher the rating, the hotter the pepper. Pimento and Banana Peppers both have a Scouville heat unit below 900, and are considered very mild chillies. In contrast, a Jalapeno has a heat unit of between 2,500- 5,000. The famous Scotch Bonnet registers between 100,000- 325,000 Scoville units. The exceptionally hot Ghost Pepper has a scale of more than a million Scoville units – that’s 400 times hotter than Tabasco sauce.

Chillies are known to have some noticeable physical effects, too – they can stimulate the body, awaken the senses, raise body temperature and stimulate the appetite by increasing the flow of saliva and gastric juices. For the uninitiated, a chili like the Ghost Pepper could even lead to blistering of the lips and palate.

I can’t take the heat!

If you like chillies and want to take on their spicy powers the best thing to do is build up your tolerance over time. Much the same way salt-free foods taste bland to people who typically sprinkle it all over everything, at first chillies can feel unbearable to someone who isn’t used to eating spicy food.

If you overdo it, try not to reach for a glass of water. This can actually spread the heat to other parts of your mouth and make it feel worse. Rather than drinking liquids, grab for absorbent foods like bread and rice to quash the burning sensation.
