Hentak

What hentak is

Hentak is a fermented paste from Manipur in north-east India. It is made from sun-dried small fish and the petioles of an aroid plant, shaped into balls or kept in an earthen pot. It works less as a finished sauce than as a seasoning base. Local writing calls it a pickle used to flavour Manipuri dishes.

The sources do not agree on the species. The 2009 study names sun-dried Esomus danricus and Alocasia macrorhiza petioles. A 2018 study names E. danricus or Puntius sophore, petioles and small onion. The 2024 survey of six villages names Esomus danricus (balloon nga or ngasang) and Puntius spp. (phoubu nga), and calls the aroid Colocasia. The botanical name conflicts between sources and has not been resolved.

Where it is eaten

Hentak flavours several Manipuri cuisines. The 2009 study notes that the balls harden over months and can be loosened with a little water for use. The 2018 study says it is eaten as a side dish or in eromba, a local dish. The state-level festival in 2020 and local women's preparation are the best-recorded modern public use.

No source gives a measured sauce or dip recipe, so the page does not offer one.

Timing and what the sources disagree on

The sources give different maturation times for hentak. One outline says the balls are ready after about a week. Another says the paste is kept in a tightly sealed earthen pot for seven to nine days. A third gives about two weeks before the product is ready to eat. A Manipur heritage blog describes balls packed into small airtight earthen pots for a week to a month. These figures are household and blog reports and are not checked against a measured endpoint.

The aroid petioles are cut and sun-dried for about one day before mixing, and the accounts give equal parts of petiole and fish powder. The fish is the Indian flying barb, Esomus danricus, sun-dried on bamboo trays and crushed. Some versions add other plants, including Colocasia esculenta.

Microbes the research names

A 2016 review of ethnic fermented fish products from India and Nepal lists lactic acid bacteria in hentak, including Lactobacillus plantarum and Lactobacillus lactis, along with other lactobacilli and yeasts. These are the organisms named in that review; the review does not give a home endpoint or a shelf life, and no source here establishes safe keeping at room temperature.

Method

Hentak is a Manipuri seasoning paste of sun-dried fish and aroid petioles. The 2009 account describes sun-drying the fish to powder, cutting and sun-drying the petioles, crushing equal weights, shaping balls and sealing them in earthen pots for about two weeks. A 2024 survey of six villages describes ten days of fish drying and one to two weeks of sealed fermentation at room temperature.

The sources do not give masses, moisture endpoints, temperatures or salt levels, so no safe-storage limit can be set from them. Lactic acid bacteria, including Lactobacillus plantarum, are named in a 2016 review, but no source ties a starter or a condition to a safe outcome.
