Air Fryers

It seems like everyone’s talking about air fryers. They were recently dubbed the product that defined 2021, with sales up by 400%. But how do they fry with air?

Listener Sally in Harrogate has another question too: at a time when the cost of living is rocketing will cooking with an air fryer save her money?

And, because they use little to no oil, is cooking food in an air fryer also “healthier”?

Greg Foot investigates, speaking to a food scientist at Imperial College London and the BBC’s Good Food Magazine, to find out whether the claims being made around air fryers live up to the hype or are just marketing BS.

Sliced Bread

While Sliced Bread takes a break we serve up… Dough.

Dough is the series from BBC Radio 4 which looks at the business behind profitable, everyday products and considers how they might evolve in the years to come.

In each episode, entrepreneur Sam White speaks to industry experts to find out how these products manage to make a profit and what game-changing - and pointless - innovations they have seen in their time.

Tom Cheesewright, a technology expert and applied futurist, then offers his predictions on what might be coming beyond the current production pipeline.

Episodes of Dough are released weekly on Thursdays wherever you get your podcasts. But if you’re in the UK, you can listen to the latest episode on BBC Sounds first, a week earlier than anywhere else.

Produced by Jon Douglas. Dough is a BBC Audio North production for BBC Radio 4 and BBC Sounds.

Sliced Bread returns for a new batch of investigations in April when Greg Foot will investigate more of the latest so-called wonder products to find out whether they really are the best thing since sliced bread.

In the meantime, Dough is available in the Sliced Bread feed on BBC Sounds.
