Origin
Sardinia — the myrtle (mirto) is the most characteristic plant of the Sardinian macchia, and its use in cooking, liqueur production, and post-roasting flavoring is unique to Sardinian culture. The myrtle-rest technique is specific to porceddu and to some lamb preparations in Sardinia.
Description
While porcetto allo spiedo (spit-roasted suckling pig) is the most famous Sardinian meat preparation, porceddu al mirto is its complement: the roasted suckling pig rested under a blanket of fresh myrtle branches for 20-30 minutes after cooking. The myrtle (Myrtus communis) grows wild throughout Sardinia and its volatile aromatic compounds (eucalyptol, limonene, α-pinene) transfer to the hot pig skin during resting, infusing the meat with a complex herbal, citrus-pine fragrance that is unmistakably Sardinian. The myrtle rest is what distinguishes Sardinian roast pork from all others.
The Thread
Flavour Context
Porceddu al mirto has a specific, complex aroma that no other preparation replicates — the crisp, golden skin carries a pine-citrus-herbal perfume from the myrtle that is distinctly Sardinian. The flavour of the meat itself (the suckling pig's sweetness from the milk diet) is accented rather than dominated by the myrtle. It is the flavour of the Sardinian island — its macchia, its light, its particular air.
