When you unwrap a piece of Su Entu, you can almost smell Sardinia. It smells of sea breezes, dusty earth, fresh grass and wildflowers. It is a firm cheese and, like the island itself, is dry and craggy. It tastes pleasantly sheepy, very savory, and nutty like brown butter. Drizzle it with olive oil or honey (or both!), to add a richer texture and a touch of sweetness to this Sardinian wonder.
