But what exactly are they? Why the cult following? And why is the UK the unlikely second home for this Indian snack sensation?

Over the past three decades, the British palate has become increasingly adventurous. The nation has long declared an unofficial national dish. It was only a matter of time before that love for spicy, savoury flavours moved from the main meal to the snack aisle.

Open the pack, sprinkle over a bowl of instant noodles or a cheese toastie for a spicy crunch.

However, for the growing legions of fans, the pain is the point. It’s a clean, crisp heat that doesn't linger unpleasantly but leaves you reaching for "just one more."

They’ve successfully bridged the gap between Indian street food heritage and modern British snacking culture. They are crunchy, they are spicy, and they are undeniably addictive.
