The chillies that shape everyday cooking

Most people meet Capsicum annuum long before they realise chillies come in species at all. It’s the plant on the windowsill that gets on with things. Seeds sprout without drama, leaves appear in tidy pairs, and before you’ve quite decided where to put it the plant has quietly produced a chilli just to prove the point.

Everything about it suggests cooperation. The stems grow upright, the branching is sensible rather than ambitious, and the fruits hang or stand exactly where a human would have placed them. Even the flowers — plain white stars with no theatrical spots or colours — look like they’ve come to work rather than perform.

    Turkish Pointed chilli

  • capsicum annuum Why does it grow like that?

    Where it comes from

    Originating in the drier regions of Mexico and the southern United States, annuum learned to live with seasons — warm days, cooler nights, and weather that doesn’t wait forever. So it hurries: flower early, fruit quickly, make seeds before conditions change.

    That urgency is why it behaves so well in Britain. While other species negotiate with the climate, annuum simply gets started.

  • capsicum annuum So what’s the point of it?

    The takeaway

    Other species have signatures. Capsicum annuum has range. It contains the peppers that fill markets, anchor sauces, dry into powders, and roast into whole meals — and it also contains plenty of varieties with their own quirks and personalities.

    Calling it “common” is just shorthand for “everywhere, because it works in a hundred different ways”, and it rarely punishes inexperience.

    All time favourite: Jalapeno

Capsicum annuum was domesticated in Mexico around 8,000 years ago and spread throughout the Americas. After the Columbian exchange in the 16th century it was carried worldwide through trade.

Scoville Heat Units (SHU) measure how hot a chilli feels — essentially how much capsaicin it contains. A Moruga Scorpion at about 2,000,000 SHU is roughly four hundred times hotter than a jalapeño at around 5,000 SHU.
