Tungrymbai
A Khasi and Jaintia fermented soybean food from Meghalaya: cooked beans ferment naturally in leaf-lined baskets above a fire, giving a sticky, pungent, savoury mass.

Lung-seij · Lungseij · Lung-Siej
Young Dendrocalamus hamiltonii shoots fermented in a bamboo cylinder in a stream or in a sealed bottle above a kitchen oven, from Khasi households in Meghalaya.
Safety note
Bamboo shoots can contain cyanogenic glycosides. Food Standards Australia New Zealand says bamboo shoots must be fully cooked before eating and gives general preparation guidance for fresh shoots. That guidance does not establish a cooking time or detoxification endpoint for fermented Lung-siej. The 2009 Lung-siej account reports neither a measured cyanogen result nor a validated safe-use endpoint for its two traditional variants. Read the method below as cultural documentation, not a tested household process.
Overview
Lung-siej is a fermented bamboo-shoot food of the Khasi hills in Meghalaya. The 2009 survey separates it from other bamboo ferments of the region, and the atlas keeps it apart from the other products.
The 2009 account describes two vessel traditions: a stream-immersed bamboo cylinder and a glass bottle kept near a kitchen oven. It does not validate a storage period or a safe endpoint for either variant.
Methods
The two arrangements are described here as cultural process details, not as validated home procedures. The source gives no weights, yields, measured fermentation endpoint, cyanogen result or safe-storage guidance.
The survey gives no weights, yields or measured endpoint for either method.
Use
The survey says Lung-siej is eaten in curry with meat and fish. It is a use context, not a recipe.
History
The 2009 survey names Khasi women as the main producers. The food is eaten in curries with meat and fish and sold by women in Meghalaya local markets. The source gives no harvest calendar.

Risks and precautions · Elevated risk
Seepage and spoilage in the cylinder method
The 2009 account notes that seepage can blacken the cylinder product. The sources give no validated control against this.
Hazard sourceCyanogenic glycosides in bamboo shoots
FSANZ identifies cyanogenic glycosides in bamboo shoots and advises full cooking before eating. Its general advice does not validate a cooking time or detoxification endpoint for Lung-siej; the cited 2009 account reports no cyanogen measurement.
Hazard sourceThe source says the bamboo-cylinder ends were sealed against stream-water seepage; this is a historical process description, not a validated safety control.
Control sourceBamboo shoots can contain cyanogenic glycosides. FSANZ advises full cooking before eating; this general guidance does not validate a cooking time or detoxification endpoint for Lung-siej.
The source describes two traditional fermentation arrangements but reports no measured endpoint or validated storage guidance. This page documents the account and is not a tested household method.
Do not treat smell, taste or appearance as proof of safety.
- Remove the outer bract sheaths from young Dendrocalamus hamiltonii shoots, wash them and cut them small.
- Cylinder method: pack the shoots tightly into a one-ended bamboo cylinder, close the rim with leaves and tie it, seal the ends against water seepage, invert it and immerse it in a nearby stream for about one to two months.
- Bottle method: pack sliced shoots into a glass bottle, add water to cover them, cap the bottle tightly and keep it above a kitchen oven for about one month.
