Hamei

Hamei and Manipur Atingba

Hamei is a natural rice-cake starter used for Atingba, a fermented rice beverage of Manipur. A 2009 account names Hamei as a flat starter cake and connects it with Atingba. A 2024 review table specifically pairs Atingba with the Meithei community in Manipur, glutinous rice and Hamei. These regional statements do not establish that every Hamei cake or Atingba preparation is the same.

Hamei belongs to a family of dried mixed starters from Northeast India. A regional survey describes it as a dry, round-to-flattened mixed-dough starter, and the research literature often treats it alongside Marcha, the better-known starter of the Eastern Himalayas.

One documented Hamei cake account

A Manipur account records one preparation using crushed raw rice with Yangli (Albizia myriophylla) bark powder. The printed bark rate is 0.25 kg/kg; the passage does not clarify a broader formulation basis or state that the quantity is standardized. The mixture is pressed into flat cakes, described as approximately 2–7 cm across and 0.6–1.5 cm thick. They are kept over rice husk in a bamboo basket for two to three days at room temperature. The account describes swelling, alcoholic aroma and yellowish color as desired characteristics, followed by drying; it says Hamei is mostly prepared in summer (May–July) and that dried cakes are stored year-round.

Other accounts of the cake

A 2018 regional survey gives a second, shorter description. It names local rice, yangli bark and a small proportion of old Hamei as the ingredients, followed by fermentation of the shaped dough in a basket with husk and then sun drying. The old Hamei is the carry-over of the previous batch's microbes, which is how such starters are kept going between seasons.

A separate case study of Meitei fermented foods describes another rice-and-yangli preparation and notes that drying depends on the weather. It places the beverage context in Sekmai and Awang Sekmai. The accounts differ in detail and none gives a validated endpoint, so they should not be combined into one recipe.

Atingba use is a separate measure

For one Atingba batch, the 2009 account reports crushing five Hamei cakes and mixing the powder with 10 kg cooked, cooled glutinous rice. It gives the cake count but not cake mass, a chemical specification or a batch-independent potency measure. This recipe-line observation does not establish a universal starter dose or make the beverage's fermentation stages part of Hamei manufacture.

What laboratory studies found

Researchers have isolated yeasts from Hamei and identified them by molecular methods, and have isolated lactic-acid bacteria from Hamei and Marcha. Separate work has profiled the fungal communities of Hamei samples by high-throughput sequencing and has isolated filamentous fungi from it. Findings vary with sampling and method.

One brewing study used Hamei-derived isolates in a controlled black-rice-beer comparison with an established starter. Its shelf-life results concern that finished experimental beer, not dry Hamei stock. These results describe particular samples and laboratory work; they do not show that one organism is universal to Hamei or should be used alone as a starter.

Study samples and places

A 2018 Northeast India survey included five Hamei samples in a set of 40 dried starters from eight states, collected after preparation from local people. Studies of Hamei report sampling at places such as Andro, Kangchup, Kakching and Phayeng. These are study sites, not proof of a sole birthplace, and they do not identify a single village of origin or establish that all Hamei has one microbial composition. The 2018 Meitei case account does not establish that every Hamei maker belongs to one community.

Limits of the available evidence

The consulted sources provide cake-making accounts and one beverage-use measure, but not a unique origin, a universal formula, a validated starter-quality test, objective drying endpoints, tested storage conditions or food-safety controls. The reported appearance and aroma cues are observations in the cited account, not proof of safety. Local-language forms and community variation need further evidence. No instructions for renewing or storing Hamei are given here.
