Flavor that resonates

Colatura, the traditional anchovy sauce of Cetara on the Sorrento Peninsula, is a powerful condiment -- just a few drops will give a dish a rich savor. That’s fortunate, because this handmade product is in limited supply. It’s mostly sold in one-tenth-liter (3.38-ounce) bottles. Two of the four brands recognized by the Friends of the Anchovy (Amici delle Alici) in Cetara are available online.

Nettuno di Giordano is $22

a bottle at www.amazon.com, $25 at www.gustiamo.com and $35 per bottle at www.zingermans.com. Delfino Battista is $11.50 a bottle at www.buonitalia.com.
