What is it?
A rich, dark vinegar with a lingering smoky sweetness; northern China's knee-jerk accompaniment to dumplings, noodles, soups and braised eggplant dishes. The best is Chinkiang (Zhen Jiang) vinegar from the eastern province of Jiangsu, made from black glutinous rice, water, sugar and salt.
Why do I care?

Because it's black magic. Just a dash transforms oysters, soups and noodle dishes, cuts through fatty pork and does wonders for salads. Serious addicts carry a small bottle at all times in case they meet a boring dumpling.
Can I do it at home?
Certainly. Chinkiang sells for $3 in Asian food shops and will last for years. And, because it's good for the digestion, blood pressure, colds and flu, so will you.
Where is it?
''It's the quintessential Chinese vinegar'' says Dan Hong, of Mr Wong. ''For the Cantonese it's more about red vinegar, but for the rest of mainland China, it has to be black. I love it with Shanghainese xiao long bau dumplings and Sichuan hot and sour soup''. Chef Jin Kung, of LL Wine and Dine, in Potts Point, sends out crisp pork belly in a syrupy dressing of black vinegar, palm sugar and kaffir lime leaf, topped with mint, coriander, chilli and crushed peanuts. ''It's a lovely ingredient,'' says co-owner Tim Barge. ''Once you've tried it, you can't go back.'' Michael Drescher, of Johnny Wong's Dumpling Bar, in Darlinghurst, agrees. ''We put it out on the tables for people to add to the dumplings, and go through three or four bottles a night,'' he says. ''In the kitchen, it's used for marinades, rice paper rolls and for the Asian vinaigrette in our roast duck and pomelo salad.''
At the Potsticker in Caulfield North, black rice vinegar is the natural accompaniment to the pan-fried dumplings. ''It's a very traditional pairing,'' says owner Eric Wong. Chef Dai Duong, of Geoff Lindsay's Dandelion, teams it with smoked eggplant, spring onions and chilli in a slow-cooked claypot. ''It's almost like an Asian balsamic vinegar,'' he says. ''Normal vinegar just wouldn't do it.'' Leigh Power, head chef of Gingerboy, celebrates its ''mellow, malty, woody, smoky'' qualities with his dish of slow-roasted pork belly with spiced black vinegar caramel and heirloom tomato salad. ''It's like a modern play on sweet-and-sour pork,'' he says. ''You get the sharpness coming from the vinegar, the sweetness from the caramel, and the freshness of the tomatoes and herbs on top.'' Power has even used black rice vinegar, palm sugar and vanilla to macerate strawberries for dessert.
