The Italian Tool We Rely on to Make Perfect Pesto

Nothing's better for basil than a marble-and-wood mortar and pestle set

Carrara appears a city dominated by icy mountains. They loom above, menacing and craggy, and somewhere a drill is buzzing, a constant crash of metal against rock. Everything—the trees, the asphalt, the windshield—is covered in a fine, white chalk.

Up close, it becomes clear that the mountain faces are not actually blanketed in snow. This is raw marble veined with white and cream, dark gray, and blue, neat and jagged as slate shingles. Harvested just over the Ligurian border in northern Tuscany for thousands of years, marble has been the basis of the economy in this obscure corner of Italy since Roman times.

For centuries, it's been sculpted into putti, carved into columns, and chiseled into the shape of mortars, the bowls of which have been perpetually filled and refilled with basil, salt, oil, cheese, garlic, and nuts, then pounded with a wooden pestle (marble would be too heavy and violent against the basil).

WATCH: How To Make The Perfect Pesto

When our test kitchen was refining a recipe for Ligurian pesto, we kept noticing how much we preferred batches made with a marble mortar and a wooden pestle compared to stoneware or a molcajete . (A food processor doesn't even come close.) The sauce was gently muddled and smooth, but also perfectly inconsistent, pasta-coating but not quite pasty.

We are mortar and pestle evangelists generally, and have a growing collection of styles for different uses. As a more budget-friendly option, this porcelain model is the next best thing to a real (and expensive) marble version. But if you want to make pesto as they do in Liguria, spring for the marble as a new kitchen essential. It will pay you back with better pasta forever.
