Guizhou, shared across Miao, Yi and Han tables in the province, and named among Guizhou's own "hardest to eat, most loved" dishes.
As tradition built it
Serves 4 as a side. 10 minutes.
Ingredients
- 150 g fresh zhergen root (houttuynia cordata), where obtainable, or see Sourcing for the honest gap
- 1 tbsp crushed dried chilli
- 1 tbsp light soy sauce
- 1 tbsp rice vinegar
- 1 clove garlic, minced
- 1 tsp sugar
- 1 tsp toasted sesame oil
Method
- Trim and wash the root well, then cut into roughly inch-long pieces.
- Salt lightly and leave 5 minutes, then drain any liquid released.
- Dress with the chilli, soy sauce, vinegar, garlic, sugar and sesame oil, tossing well.
- Serve immediately as a palate-clearing side, the dish's genuinely divisive, medicinal-sour flavour meant to cut through richer dishes on the same table.
What a modern chef changes
A texture the traditional dish never had, built from the same flavour.

Method
- Where fresh zhergen root cannot be sourced (the honest, common case in Britain), dehydrate thin slices of a milder relative or, more usefully, build the dressing's flavour profile (chilli, garlic, vinegar, a controlled fermented element) into a standalone condiment rather than pretending a substitute root replicates the plant.
- Emulsify the dressing in a high-power blender with a little extra oil until it forms a stable, pourable sauce rather than a loose dressing, then pass it through a chinois for a completely smooth finish.
- Serve as a dressed carpaccio-style plate where fresh root is available, thin-sliced on a mandoline rather than chunked, letting the dressing coat a larger surface area for a more even hit of sourness per bite.
