INGREDIENTS
Ingredients
River snails, zaolu brine and seasonings; alcohol may remain.
THE LOCAL LENS · SHANGHAI
A cold dish with a wine-making vocabulary.
Zao refers to rice-wine lees and their aromatic brine. It does not mean the snails are served raw.
Three things to know
- Zao describes a wine-lees preparation.
- Cold serving does not imply raw cooking.
- Alcohol and mollusc checks matter.
Try noticing
Separate the wine-like aroma from the snail’s firm texture.
The story behind this bite
Shanghai’s general gazetteer lists zaotianluo among the city’s snacks. The detail to keep is the technique: cooked food gains another layer through aromatic brine. A note about aroma or texture can sit beside that craft, without inventing a historic restaurant visit.
At the counter
Ask for thoroughly cooked snails before marinating. Check alcohol and mollusc ingredients; brine is not a substitute for cooking.
