The Science of Heat: An Interview with Tim McCarthy and Jay Rayner
If you’re a lover of all things hot and spicy, you’ll enjoy this fiery tale from Northern Ireland’s very own heat master, Tim McCarthy, the owner of Black Fire Foods. Recently, Tim sat down with renowned food critic Jay Rayner alongside Professor Barry Smith, culinary expert Rachel McCormack, acclaimed chef Rob Owen Brown, and the queen of Ulster cuisine, Paula McIntyre. Their mission? To delve into the science of what makes chillis hot and explore the burning sensation we all chase.
The Kitchen Cabinet Special Broadcast on 12 February 2019, this special episode of The Kitchen Cabinet was a deep dive into the magic of chillis and the infamous Scoville scale. For the uninitiated, the Scoville scale measures the heat level of chillis by quantifying capsaicin, the active component responsible for that flaming kick.
Tim McCarthy’s Hottest Hot Sauce In the heart of the discussion, Jay Rayner and the panel got a taste of Tim McCarthy’s hottest hot sauce—a bottle that’s not just a condiment but an experience. Known for pushing the boundaries, Tim’s creations are legendary in the chilli community. This particular sauce isn’t for the faint-hearted, and the panel was sweating, wide-eyed, and thoroughly impressed.
“There’s a fine line between pleasure and pain when it comes to chillis,” Tim joked, “and we love walking that line.”
In The Science Behind the Heat, Professor Barry Smith explained why we feel an unmistakable burn. Capsaicin triggers the same receptors in the mouth that respond to heat, tricking the brain into thinking the mouth is on fire—an illusion that chilli enthusiasts can’t seem to get enough of. This unique reaction makes tasting sauces like Tim’s both exhilarating and memorable.
An Experience Worth Sharing Rachel McCormack and Rob Owen Brown shared their insights on how chillis enhance and transform dishes. At the same time, Paula McIntyre praised the bold, fearless approach of local producers like Tim. “It’s not just about heat,” she said. “It’s about flavour, depth, and that unexpected twist that lingers.”
Whether you’re a seasoned spice fan or just curious about the science behind that kick, this episode of The Kitchen Cabinet, aired on 12 February 2019, is worth revisiting. And if you’re brave enough, seek out Tim’s hottest sauce for a taste of Northern Ireland’s chilli prowess.
