Hamei
Hamei is a Manipur rice-cake starter used for Atingba. Accounts of how the cakes are made differ, and microbial studies describe particular samples; none defines a universal formula or safety standard.
Cultures
Thiat
Thiat is a dried mixed starter used for alcoholic beverages in Meghalaya. Field accounts differ and laboratory studies describe particular samples; none gives a universal recipe or validated household method.
A Meghalaya starter in distinct local contexts
Thiat is a dried amylolytic starter, one whose microbes break starch down into fermentable sugars, used for alcoholic-beverage production in Meghalaya. A 2007 field account documents its preparation among Pnar communities in Jaintia Hills. A later regional study places Thiat in Meghalaya without naming a specific community in its Thiat passage. The evidence documents occurrence, not one birthplace or a uniform cake.
What the field accounts record
The 2007 account reports local red rice, Khaw-iang leaves, water, and wood and bamboo tools in one Pnar Thiat preparation. A separate overview describes glutinous rice with dried Khaw-iang leaves and roots, followed by fermentation and drying. The two accounts differ in detail, and neither gives a validated household method, an objective drying endpoint or a storage duration, so they should not be combined into a universal process.
Starter, mash and beverage are different things
In the 2007 Kiad account the names mark stages. Thiat is the starter cake. Jyndem is the fermented intermediate made with it, Sadhiar the fermented drink extracted from it, and Kiad the distilled product. The paper also describes Kiad's social and cultural use among Pnar communities in Jaintia Hills. Thiat itself is only the first of these.

Microbial findings are sample-specific
A comparative sequencing study reports different community profiles in its Marcha and Thiat samples, with more moulds than yeasts in the Thiat samples. Another study reports Thiat-associated yeast isolates from a Northeast Indian sample set. This is why Thiat is described as a mixed starter and not as a pure yeast: moulds and yeasts are both reported in the sampled cakes. The results describe the studied samples and methods; they do not define a universal culture or recommend an isolate for food use.

Evidence limits
The sources do not establish a unique historical origin or a seasonal calendar for making Thiat. Neither field account provides process-specific safety controls. Community-specific names and variation beyond the Pnar and Jaintia Hills account need local evidence and community review. No instructions for making, renewing or storing Thiat are given here.
