Tweets of the week: What is crostata and why is it making Elisa Longo Borghini win?

"I did it for the crostata." These were the words uttered by Elisa Longo Borghini in the moments after she won the Tour of Flanders .

At the time, I didn't think much of it. I didn't know what crostata was, and it seemed like a passing comment, an inside joke perhaps. Then the Italian won again, and said it again.

This time it was at De Brabantse Pijl, earlier this week, where she soloed clear and won by 41 seconds. Why did she do it? "Only for crostata!" she wrote on X. As a capital-J journalist, I figured it was time for an investigation.

First, I had to figure out what crostata was. This was the easy part. A quick Google search returned countless images of pies, the sweet, crusty type that get left on windowsills in cartoons.

Wikipedia then stepped in. Crostata is a sort of fruit tart, an Italian dessert, that dates back to a 15th century cookbook, it told me. Almost all of the pictures show it to be topped with a lattice design, so I assume this is the going technique.

Facts established, the big question remained: why is it helping Longo Borghini win bike races?

I turned to Lidl-Trek’s press officer, Amy Cameron, for the answers. "It is a winning treat," she explained, one made by the team's chef, Mirko Sut. I asked if she has ever tried it. "Have I tried it?" she scoffed. "I’ve been eating Mirko's crostata longer than Elisa when me and him were on BMC together! It is delicious."

Suddenly, everything made sense. The dessert isn't a performance nutrition fad. No, it's a positive reinforcement ruse, a Pavlovian trick as old as time. Win race, get crostata. Longo Borghini had cracked the system.

I wanted to know more. Is there a secret ingredient? Does Sut do something special to the crostata? "He just perfected it, I believe," said Cameron. "He makes this incredible pistachio one that is unreal." The recipe, however, is top secret.

So there you go. For anyone wondering how SD Worx-Protime could be beaten this year, the answer wasn’t race tactics or newfangled tech, it was the lure of a simple, Italian dessert. Crostata, Lidl-Trek’s secret weapon.
