We’ve used the internationally recognised Scoville scale to help you figure out the best type of chilli to add to your dinner. The scale measures the concentration of capsaicin (the chemical compound that causes spicy heat) in a pepper. The world’s hottest chilli has a rating of 15,000,000 and a jalapeño is 2,500. Anything above 80,000 is considered ‘very highly pungent’. Ready to turn up the heat?

Ancho chillies are some of the mildest chillies on the scale. They are usually sold as a paste, powder or dried, and in that case will need to be rehydrated before you can eat them, which you can do by covering them with boiling water for 20 mins. Drain the water then chop the chilli, removing the seeds and stalk. This dark black-red chilli will add a fruity, smoky finish to your meals and works well in Mexican dishes.

How to prepare chillies
- Start by slicing the stems off the top of the fresh chillies. Then, cut each chilli in half lengthways and scrape out all the seeds and light-coloured membrane from both sides, if you like less heat.
- Cut the chilli into fine strips by slicing it widthways, unless the recipe calls for the chilli to be finely diced. In this case, slice it lengthwise into long, thin strips. Bunch the strips together and finely slice across them widthways. Top tip: putting the chilli skin-side down on the chopping board makes it easier to slice.
- Can you freeze fresh chillies? Yes, in several different ways. If you’re working with the sliced variety, simply place the leftovers on a baking tray and pop them in the freezer. Once they’re frozen, store them in a reusable container for later. You can also preserve chillies by adding them to an ice cube tray with cold water and leaving them to freeze.
