Dhokla is Gujarat’s steamed, spongy, savory cake: a fermented batter of split chickpeas (chana dal) and rice, steamed, cut into squares and finished with a sizzling tempering of mustard seeds, curry leaves and green chili. It’s eaten for breakfast and as a snack with green chutney. India has many fermented cereal-legume foods like it – idli and dosa in the south, dhokla in the west (Tamang, 2022).
Khatta Dhokla vs. Khaman
The bright yellow, very fluffy squares sold as “dhokla” outside Gujarat are usually khaman, made from chickpea flour (besan) raised quickly with baking soda or fruit salt (Eno) – no fermentation needed. Traditional khatta (“sour”) dhokla is made from soaked and ground chana dal and rice, fermented overnight until sour and bubbly. Both are good; this recipe is the fermented one. Either way it’s steamed, so dhokla contains no live cultures – fermentation’s role is flavor, texture and changes to the batter.
What Fermentation Does to the Batter
- Antinutrients fall. In a study optimizing dhokla, soaking, fermenting and then steaming the batter for 20 minutes cut tannins by 100%, phytic acid by 94%, trypsin-inhibitor activity by 92% and total biogenic amines by 20% compared with the raw ingredients. Amines actually rose during fermentation and fell again on steaming – a reason to steam fully (Sharma et al., 2018).
- More phenolics. Fermented dhokla and idli batters had more than 2.5 times the total phenolic content of unfermented batters (Moktan et al., 2011).
- Not a mineral boost. Fermentation increased the zinc and iron available from idli and dosa batters, but not from a dhokla-type batter of chickpea, green gram, black gram and rice, which kept much of its phytate (Hemalatha et al., 2007).
Tips
- Ferment somewhere warm (about 25–30°C); in a cool kitchen use an oven with just the light on.
- The batter should be bubbly, slightly risen and pleasantly sour – not putrid.
- A pinch of baking soda stirred in just before steaming is common at home for extra lift; it doesn’t replace the ferment.
- Steam over steadily boiling water and test with a knife: it should come out clean.
