Cast your mind back to the spring of 2020. The country was locked indoors, flour had vanished from the supermarkets, and Google searches for “sourdough” reached their highest recorded level. Millions of people who had previously treated their kitchens as somewhere to store takeaway menus began asking an unfamiliar question: why does this actually work?

We talk less about the pandemic anymore, but some of its effects are still sitting in plain view.

One of them is the continued rise of “science cooking”: recipes that explain not just what to do but why it works. The theory is simple: a cook who understands the mechanism will outperform one who merely follows instructions. The genre’s founding modern text is The Food Lab, a 958-page book by the American chef J. Kenji López-Alt (pictured), which won a James Beard Award on publication in 2015 and sold its millionth copy in late 2024. Cookbooks do not usually behave like that a decade after release.

Here is the part that interests us. López-Alt’s authority does not come from asking you to take his word for anything, it comes from showing you the work. He cooks the same steak six different ways on camera and lets you look at the results. The authority lives entirely in the demonstration. You could run the experiment yourself. Almost nobody does, of course. The point is that you could.

Britain got there early, in its own way. Heston Blumenthal was applying laboratory method to dinner while most of us were still suspicious of garlic, and his Waitrose years took the idea mainstream. But Heston’s science was still largely a spectacle to be admired. The newer version hands you the apparatus in your own home.

Now set that against the received wisdom about experts. Michael Gove told us in 2016 that people in this country had “had enough of experts”, and many trust surveys since have pointed in a similar direction. And yet a chef with a chemistry habit sells a million copies of a book about why brining works. Have we really had enough of experts? A better answer may be: we have had enough of being asked to take things on trust.

Fiction noticed the same thing. Lessons in Chemistry, Bonnie Garmus’s novel about a 1950s chemist who ends up fronting a television cooking show, became one of the biggest-selling books of 2022 and an Apple TV+ series the year after. Her heroine’s radical act is to treat an audience of housewives as adults entirely capable of following the chemistry, while every institution around her assumes otherwise. Several million readers recognised the appeal.

Which brings us, eventually, to money. We can see the faint irony in a wealth management firm writing warmly about scepticism towards professionals. But the analogy still holds because good advice should not depend on deference. Financial advice has historically run on the older model of authority: the professional recommends, the client is supposed to trust, and much of the working stays out of sight. That model needed high public trust which is no longer on offer.

The advice that earns confidence now looks more like the steak cooked six ways. What the portfolio holds, and why it holds it. What the charges pay for. What would knock it off course, and how to spot it early. A recommendation should become stronger when asking questions, not weaker.

So when we walk a client through the reasoning rather than past it, that is the model we are borrowing. Show the mechanism. Invite the questions. Scrutiny is not a challenge but how trust is built.

It may take longer than asking to be trusted but, the results tend to last.

 

The people who made cooking a science

If the genre has a centre of gravity, it’s a handful of names. Here are the ones worth knowing.

Ethan Chlebowski — https://www.youtube.com/channel/UCDq5v10l4wkV5-ZBIJJFbzQ
An engineer by training, which tells you most of what you need to know. His comparison-cooking format asks the same question every time. Why does this work, and how would you know?

Adam Ragusea — https://www.youtube.com/@aragusea
A former journalism professor who quit the day job when the channel took off. He has a gift for poking at kitchen habits everyone assumes are settled, and occasionally being proved right.

America’s Test Kitchen — https://www.youtube.com/@AmericasTestKitchen
Not a person but an institution, and the one people reach for when they mean rigour. Every recipe is tested until it stops arguing back.

Chinese Cooking Demystified — https://www.youtube.com/@ChineseCookingDemystified
The same investigative instinct pointed at a single cuisine, with a seriousness about sourcing and technique that most channels never attempt.

Chris Young — https://www.youtube.com/@ChrisYoungCooks
Co-author of Modernist Cuisine and now the mind behind a cooking thermometer that treats temperature as data. The most literally scientific of the lot.
