What's The World's Thinnest Pasta Shape?

* Disclaimer: Although scientists have created what they nickname "the world's thinnest spaghetti," it is not edible. For that reason, this article is only concerned with pasta that you can sit down to eat. 

Capellini ("angel hair") is commonly cited as the world's thinnest pasta shape. However, the accolade goes to su filindeu, an unfathomably thin type of pasta that also happens to be the rarest and most expensive pasta shape on earth.

There are plenty of pasta shapes that qualify as "thin." Linguine, pici, and vermicelli are among our favourites, but ask anyone to name the thinnest pasta shape on earth, and you'll almost certainly get "spaghetti," or at best, "angel hair," as the reply. As it turns out, though, a couple of extraordinary shapes are even thinner.

With its ultra-thin strands, Angel hair (Capelli d'angelo in Italian) is often called the world's thinnest pasta shape. We've no idea where they get the numbers from, or what qualifies them to come up with such a rigid definition, but some pasta experts state that the thickness of the angel hair strands must be between 0.78mm and 0.88mm for it to be worthy of the name.

There's no doubt that angel hair strands are insanely thin. They need just minutes to cook, and as we've found out the hard way, they turn from being beautifully al dente to inedible mush within seconds if you don't watch them like a hawk.

However, one pasta style beats angel hair, hands down. The accolade for earth's thinnest (and rarest) pasta goes to su filindeu. The tiny strands are so challenging to create that the secrets to making them are known to just a handful of women in a remote part of Sardinia.

Hold a sheet of it up to the light, and you'll think you're looking through translucent silk rather than pasta. We consider it one of the finest examples of intuitive cooking in the gastronomic world.

Only expect to be able to enjoy su filindeu with some serious legwork. It's a nightmare to get hold of, and you'll have to max out your credit card if you find some for sale.

We're lucky enough to have been able to track it down and cook with it, and we documented our riff on a very su filindeu recipe here.
