Garlic-Sauce Sliced Pork

Sliced 'white meat' (白肉) descends from the boiled sacrificial pork (跳神肉/胙肉) of Manchu shamanic rites in the northeast; the dish appears as early as the Song-dynasty capital memoir Dongjing Meng Hua Lu. A plain-boiled 'white-boiled pork' method (白煮肉法) is recorded in the Sichuan cookbook Xingyuan Lu, compiled from his father Li Huanan's notes and published by Li Diaoyuan in 1782. By the late Qing, Fu Chongju's 1909 Chengdu gazetteer Chengdu Tonglan lists 'white meat' and 'spring-toona white meat' (椿芽白肉) as common Chengdu fare. The cold garlic-sauce-and-chili-oil rendition known as 蒜泥白肉 took its modern Sichuan form in the Republican era, finished with a re-cooked sweet soy unique to Sichuan cold dishes.

The pork is sliced as thin and broad as it can be cut with the skin still attached — large, near-translucent sheets, often each slice folded over a baton of cucumber or rolled. It is served cold or at room temperature, never in broth. The first taste is the raw bite of garlic, then a rounded sweetness from the soy, then the slow warmth of chili oil; the fat is soft and clean, not greasy. A good plate has slices so thin the red sauce shows through the meat.

Two things make the dish: the poach and the sauce. The belly is simmered whole at a bare tremble (微沸), not a hard boil, with ginger, scallion, and wine — violent boiling tightens the muscle and squeezes out juice. After it is just cooked, the heat is killed and the meat steeps in the hot liquid (焖) so residual heat finishes it gently and it stays moist; a brief chill firms the fat so it slices clean and thin. The sauce is built on 复制酱油 — soy sauce re-cooked with brown or rock sugar and spices (star anise, cassia, etc.) until reduced by a third to a half, giving a thick, sweet-salty soy. Mashing the garlic raw (not slicing) ruptures its cells so alliinase converts alliin into allicin, the sharp volatile compound that defines the 蒜泥 flavor type; the chili oil (红油) layers a separate roasted-chili aroma over it.
