Kahudi
Kahudi is an Assamese mustard-seed condiment fermented with sour Thekera fruit into a strong mash; household methods and study results differ, and no validated home schedule exists.
Kharoli
Khar-oli · Behua (a local name in one account)
A strong Assamese condiment of mustard seed mixed with khar, an alkaline banana-ash filtrate, wrapped in leaves and fermented in bamboo over a fire or in a kitchen pot.
Overview
Kharoli is a mustard-seed condiment from Assam. Its character comes from khar, an alkaline filtrate of banana ash, which is why the atlas records it as an alkaline ferment and not an acid one.
Sources describe it as a pungent condiment or a side dish eaten with rice, served with an Assamese meal.
Methods
The Jorhat households' method washes and drains the seed, pan-fries it and pounds it, sometimes with mustard oil. The paste is mixed with oil, khar and salt, shaped into balls, wrapped in softened banana leaves and fermented in bamboo cylinders over a fireplace.
The Kokrajhar survey describes a kitchen earthen-pot method for fifteen days. A separate account uses three days of sun exposure. These are kept as separate variants.
Microbiology
The Jorhat study reports a mildly alkaline sampled product at pH 7.6. Its 16S amplicon sequencing found Firmicutes and Proteobacteria, with Lysinibacillus prominent in the sampled Kharoli. These are results for the sampled material and do not define a starter.
History
The Jorhat study places the process in Jorhat district and the Kokrajhar survey places Kharoli in Kokrajhar district. One blogger's account calls a locally named Behua another name for Kharoli, but the source does not establish that.

Risks and precautions · Elevated risk
Undefined endpoint
The Jorhat households judged readiness by local sensory and visual inspection. The sources give no objective limit.
Hazard sourceDo not treat the sensory signs or elapsed days as proof that a batch is safe. The sources give no limit.
Control sourceNo validated safety limit or endpoint is given for Kharoli. The three published methods differ and should not be combined.
Khar is an alkaline ash filtrate. The sources give no concentration or handling advice for it.
- Wash the mustard seed, drain it and pan-fry it.
- Pound the seed. Mustard oil may be added while pounding.
- Mix the paste with more oil, the khar and salt.
- Form small balls, wrap them in banana leaves softened over a flame, and pack the parcels into bamboo cylinders (bahor-chunga).
- Ferment the packed cylinders over a fireplace (dhuwa-chang). The Jorhat account gives five to seven days in summer and nine to eleven in winter, based on local advice, and sampled the product on day seven.
- Kokrajhar survey: a kitchen earthen-pot version fermented for fifteen days. Another account gives a three-day sun-exposure version.
