What's in a Chilli?
At first glance, a chilli might seem like just a small, spicy fruit—but there's a lot more to it than meets the eye. From the outer skin to the seeds and everything in between, each part plays a role in delivering that signature heat and flavor.
The question “what is chilli made of” is more than just a curiosity—it’s the starting point for anyone who wants to truly understand and appreciate this versatile spice.

The Components of a Chilli
Let’s get down to the nitty-gritty. Here’s a breakdown of what makes up a chilli:
- Outer Skin (Pericarp): This is the colorful, fleshy layer that protects the inner parts of the chilli. It contains many of the essential oils and capsaicin, which is responsible for the heat.
- Seeds: The seeds are where the majority of the capsaicin is concentrated. They’re not the main source of heat, but they do contribute significantly to the overall spiciness of the chilli.
- Pith (White Membrane): This is the white, spongy part inside the chilli. It also contains a high concentration of capsaicin, so removing it can reduce the heat level.
- Flesh: The red, orange, or yellow flesh of the chilli holds most of the flavor, color, and aroma. It's the part that gives dishes their vibrant appearance and unique taste.

So, when someone asks “what is chilli made of,” the answer isn’t just about the heat—it’s about the balance of flavor, color, and texture that comes together in every bite.
Practical Tips for Working with Chillies
If you're new to handling chillies, here are a few tips to keep in mind to avoid getting burned by the heat—or worse, burning your hands!
- Wear gloves: Capsaicin can stick to your skin, causing irritation. Using gloves while cutting chillies is a smart move.
- Keep away from eyes: Don’t touch your face or eyes after handling chillies unless you’ve washed your hands thoroughly.
- Use the pith sparingly: If you want less heat, remove the white membrane before using the chilli.
- Clean your knives and surfaces: Capsaicin is oil-based, so water alone won't wash it off. Use soap and warm water to clean anything that came into contact with chillies.
- Store properly: Fresh chillies should be stored in a cool, dry place. For longer storage, freeze them whole or chop them and store in an airtight container.

These tips will help you enjoy the flavor of chillies without the accidental burn. After all, no one wants to end up with a mouth full of fire and no idea why.
