Shiny Side Up Or Down? Chef Tom Kerridge Says We've All Been Using Tin Foil Wrong

Well that's embarrassing.

Think you know your way around a roll of tin foil? Well you might want to put your confidence on ice after Michelin-starred chef, Tom Kerridge, explained most of us have probably been using it incorrectly at home.

During the second episode of Kerridge’s new BBC Two show, ‘Fresh Start’ – where he helps eight families changing the way they eat – he casually mentioned that of course we should all be using it shiny side down.

Yes, that’s right, shiny side facing down on the tray rather than up towards you.

Kerridge says in the programme: “Now, there’s two sides to tin foil, there’s a shiny side, and the not-so-shiny side. Always remember, dull side up.”

The reason for this is because the shiny side is reflective so it is going to reflect back as much heat as possible – not ideal if you’re trying to heat something up.

Despite physics being on Kerridge’s side, people have still taken to Twitter to vent their confusion (and generally feel stupid for having used tin foil incorrectly for decades of their life).

Tom Kerridge on BBC2 just said tin foil always put shiny side down. I always have it shiny side up! Have I been doing it wrong all these years?

Me too, 40 - odd years of using tinfoil the wrong way

I've been using tin foil upside down for forty years #TomKerridge #FreshStart

Okay I use dull side up because it’s on the inside of the roll so less likely to have been touched/ contaminated. I’m pretty sure it’s makes absolutely no difference and it only looks different because of how it’s made.

Me too lol! 40 years. It's weird cos I actually stopped myself with the turkey New Year's day and stood turning the foil over and over thinking to myself I wonder which way it's supposed to go? That's the truth lol! #Spooky

There were some people who already knew how to use their tin foil – putting the rest of us to shame.

Shiny side up. It’s physics!

If you’ve trained in catering this is common knowledge

But others were insistent that it makes no difference either way.

I can’t believe it makes any difference. It’s just a way of holding heat in regardless of which way up it is.

This might be why Kerridge has a Michelin star after his name and we don’t...
