Cooking flow

Cooking steps

STEP 11 / 16

Sieve each flour

A hand shaking flour through a sieve over a bowl, with the second flour waiting in its own sieve behind
Sieve the rice flour and mashkalai flour one at a time

Sieve the rice flour and the mashkalai flour, each one separately.

STEP 22 / 16

Mix the two flours well

A whisk stirring two pale flours together, dry, in one bowl
Mix the flours well before any water goes in

Put the sieved flours together in one bowl. Mix them thoroughly while they are still dry, until the two tones blend evenly.

STEP 33 / 16

Add water a little at a time

Plain water being poured from a jug into the bowl of mixed flour
Add the water bit by bit rather than all at once

Pour water into the flour gradually, as needed.

STEP 44 / 16

Bring it together into a firm dough

Hands gathering flour and water into a compact, firm rough dough in the bowl
At this stage the dough should be firm

Work the flour and water together with your hands until they form a firm dough. If dry flour stays in the bowl and the dough will not hold, add a little more water.

STEP 55 / 16

Press with palms and fingers until soft

A palm pressing down on a ball of uncooked dough while the other hand steadies its edge
Repeated pressing turns the firm dough soft

Press the dough repeatedly with your palms and fingers. Keep going until the firm dough turns soft.

STEP 66 / 16

Divide the dough into three

Three portions of uncooked dough on the work surface, with a dough scraper to one side
Three portions of dough

Divide the dough into three portions.

STEP 77 / 16

Shape each portion into a ball (loi)

Two hands rounding one portion of dough into a ball, with the other two portions behind
Round each portion into a loi

Round each portion into a smooth ball, called a loi.

STEP 88 / 16

Dampen your hands if needed

Both hands being wet under running water before shaping
Damp hands help when the dough starts to stick

If the dough sticks while you shape it, wet your hands lightly with water.

STEP 99 / 16

Spread each ball into a round by hand

Both palms gently pressing a round of uncooked dough outward
Spread the dough gradually with palms and fingers, not a rolling pin

Take one loi and press it gently with both palms and your fingers. Spread it outward little by little into a round. Work evenly so that no holes open up.

STEP 1010 / 16

Patch any holes (optional)

A hand pressing a small flap of dough over a small hole in a thin dough round
If a hole forms, a little extra dough can close it

If a hole forms, you can close it by pressing a small piece of dough over it.

STEP 1111 / 16

Heat the khola well

An empty clay cooking surface heating over a strong open fire
Heat the khola well before the dough goes on

Heat the khola thoroughly over a strong fire. A gas burner works too. Keep the cooking surface dry, with no oil.

STEP 1212 / 16

Place the dough on the hot, dry surface

A pale, uncooked round of dough being laid on a dry clay cooking surface over a gas flame
Place the round straight onto the dry khola, no oil

Lay one shaped round on the hot, dry khola.

STEP 1313 / 16

Dry-roast the first side

One pale kalai ruti dry-roasting on a reddish-brown earthenware khola with its clay rim visible
The first side roasts against the dry clay, the top still pale

Let the underside dry-roast against the clay while the top stays pale.

STEP 1414 / 16

Turn the bread

A spatula turning a kalai ruti on a clay khola, showing the roasted brown spots on the first side
Turn the bread so the other side meets the clay

Turn the bread over with a spatula to bring the second side down onto the clay.

STEP 1515 / 16

Dry-roast the second side

A kalai ruti lying flat on a clay khola, toasted first side facing up, as the second side roasts
Both sides are dry-roasted

Dry-roast the second side in the same way, with the roasted first side facing up. Cook the remaining rounds the same way.

STEP 1616 / 16

Serve hot

A single plain kalai ruti alone on a plate
Serve it hot, on its own or with whatever you like alongside

Serve the bread hot, straight from the khola. Plain is the simplest way to eat it.

Kalai Ruti: Three Ingredients, Two Hands and a Hot Clay Khola

What this bread should keep

Kalai ruti uses only rice flour, mashkalai (black gram) flour and water. The dough is pressed and shaped by hand, not rolled, and the bread is dry-roasted on both sides on a hot griddle and eaten while it is still hot.

Two flours are sieved and mixed. Water goes in until they come together as a firm dough. Then the dough is pressed again and again with the palms and fingers until it turns soft, divided into three balls, and spread into rounds by hand, with damp hands if the dough starts to stick. Each round goes onto a hot clay khola with no oil, roasts on one side, gets turned, roasts on the other, and is served hot.

That is the whole of kalai ruti (কালাই রুটি) as it is made in Chapainawabganj, in the northwest of Bangladesh. This article follows a recipe contributed to the Bangladeshi daily Prothom Alo by Yakut Ara, a Chapainawabganj resident, in a piece titled "Chapainawabganj's Kalai Ruti" (page updated 23 September 2015). That recipe uses 3 cups of rice flour to 1 cup of mashkalai flour, with water added as needed.

The recipe deliberately leaves several things open. It gives no water quantity or water temperature, no size or thickness for the breads, no resting time, no heat setting and no cooking time per side. It also does not say how large its "cup" is. This article keeps those points open rather than filling them with numbers, and it does not add salt, oil, wheat flour, yeast or egg to the dough. Sekai Gohan has not kitchen-tested this recipe, so read the dough and the bread as you go.

Names and spelling

In English you will see kalai ruti and kalai roti. Kalai refers to the pulse, and mashkalai is the Bengali name for black gram (urad). Searching with "mashkalai flour" or "urad flour" makes the flour easier to find outside Bangladesh.

A Regional Flatbread of Chapainawabganj and Rajshahi

Kalai ruti is associated with Chapainawabganj and the wider Rajshahi area of northwest Bangladesh. The Business Standard (TBS) includes it among the dishes of North Bengal's culinary heritage, and the region has more than one way of putting it on the table.

It is not a bread with a single fixed formula. Published versions differ in their flours and proportions. This article does not treat any one of them as the original or as the definition of the dish everywhere in the region. It follows Yakut Ara's Chapainawabganj recipe as one complete, regional way of making it. You can read about other versions in "Other Versions and Ways of Eating" further down.

Ingredients: Rice Flour, Mashkalai Flour and Water

Rice flour and mashkalai flour in two separate dry bowls, with an upright jug of plain water standing apart
Two flours and water, nothing else, set out before mixing

The dough has three ingredients. Add the water little by little and stop when the dough holds together firmly.

Equipment

  • Sieve
  • Mixing bowl
  • A food-use clay khola (earthenware griddle) suitable for strong heat. A heavy food-use flat pan that its maker states is suitable for the heat you will use can serve as an alternative (see the note below).
  • Spatula, for turning
  • Serving plate

Choosing the Flours and the Griddle

Flours. Look for rice flour and mashkalai (black gram, urad) flour as two separate products. South Asian grocers often stock both. Check the label of each one for allergen and shared-facility information. Neither the dish nor this recipe guarantees that the flour is free of any particular allergen.

Griddle. Use a food-use clay khola suitable for strong heat over an earthen-stove fire or gas burner. A heavy food-use flat pan is an alternative, with no guarantee of the same result. Follow the maker's instructions on heat and use. Do not put ordinary serving plates or tableware over a flame.

Method: From Sieved Flour to Hot Bread

Reading the dough instead of the clock

Judge each stage by its state: a firm dough first, then a soft dough after pressing, then a round without holes, then both sides dry-roasted. The photos show each action. They are not a guide to exact amounts, heat or doneness.

When the Dough Doesn't Behave

What you see What to try
Dry flour stays in the bowl and the dough won't come together Add a little more water and keep working it until it forms a firm dough
The dough still feels firm and stiff when you go to shape it Go back to pressing it with your palms and fingers until it softens
The dough sticks to your hands while spreading Wet your hands lightly and continue
A hole opens while spreading Press gently and evenly from the center outward. If a hole has already formed, patch it with a small piece of dough

The recipe gives no water amount, sizes or times, so these fixes are judgments made by eye and touch, not measured corrections. Because Sekai Gohan has not kitchen-tested this recipe, watch the bread rather than relying on a clock.

Other Versions and Ways of Eating

Other published proportions. Kalai ruti recipes vary. The Gastrographer publishes a version with quantities that turns the proportions around: 300 g black gram to 100 g rice, by weight. It also adds salt and specifies a water amount, a number of breads, resting and cooking times, and a bharta to serve alongside. The page does not show who wrote that recipe or whether it was tested. The Business Standard's piece on North Bengal describes a version that includes wheat flour. Both are different recipes from the one followed here. They use different units, directions of ratio and ingredients, so their amounts and steps are not mixed into this method or converted into it.

What goes alongside. The Chapainawabganj recipe mentions several things that kalai ruti can be eaten with. These include hot beef, begun bhorta (mashed eggplant), dried chilies, pickles, onion, mustard oil and coriander chutney. They are serving ideas rather than parts of the recipe, and none of them is required. The bread is complete on its own, eaten hot and plain.

Frequently Asked Questions

How big is the "cup" in this recipe?

The recipe does not say. Since the two flours are given as 3 cups and 1 cup, measuring both with the same cup keeps the proportion. This article does not convert the cups into grams or milliliters.

How much water should I use, and should it be hot?

The recipe says to add water as needed and gives no temperature. Add it little by little until the flours hold together as a firm dough.

How many breads does it make, and how large should they be?

The dough is divided into three portions. The recipe does not give the size or thickness of the finished breads, so this article does not state a yield or dimensions.

Can I make it without a clay khola?

The recipe describes a khola over a strong earthen-stove fire and says a gas stove can be used too. A heavy food-use flat pan is our editorial suggestion for kitchens without a khola. It has not been tested as an equivalent, so follow its maker's instructions on heat and use.

Can I add salt or oil?

The recipe uses only rice flour, mashkalai flour and water, and the bread is dry-roasted without oil. Versions with salt or wheat flour exist elsewhere, but they are different recipes.

Can I make it ahead or keep leftovers?

The recipe gives no storage guidance. It is meant to be served hot, straight from the griddle, so this article does not suggest storage times.

Is kalai ruti gluten-free or allergen-free?

This article makes no allergen or health claims. Check the labels of the flours you buy for allergen and shared-facility information.
