A Fermented Staple of the Nile Valley
Sudan is a country where the White Nile and the Blue Nile meet at its capital, Khartoum, and there is a dish that sits at the center of the table at every meal, morning, noon, and night. It is kisra (Kisra / Kissra / كسرة).
Kisra is a crêpe-like bread made by mixing sorghum flour with water, fermenting the batter for at least a night, and baking it thin. In appearance it resembles a French crêpe or Ethiopian injera, but the taste is entirely different. The grain-like sweetness peculiar to sorghum meets the mild sourness of lactic fermentation, and even on its own it has a depth of flavor.
Sorghum has a long history as a staple grain in the Nile region and in Africa, and fermented flatbreads made from it are part of Sudan's food culture. Dirar's study of Sudan's traditional fermented foods, The Indigenous Fermented Foods of the Sudan (1993), is a study of the subject.
The name is said to come from an Arabic verb meaning "to break or tear," because in Sudan the kisra is torn by hand and eaten with each dish. Where Ethiopian injera uses teff flour, kisra uses sorghum flour.
Search for "kisra" or "Sudanese food" in Japanese and you will find almost no proper recipes. Kisra is a good dish to get to know now, at a time when African fermented foods such as Ethiopian injera and Moroccan tagine (in Japanese) are getting attention. This article explains carefully how to re-create kisra with ingredients you can find outside Sudan and how to experience a Sudanese table.
Ingredients (serves 4, about 12 crêpes)
Sorghum flour is sold in natural food stores and online, under names such as sorghum flour, milo flour, and white sorghum flour. White sorghum flour for baking is the most widely sold. If you cannot find it, a combination of 200 g whole wheat flour and 100 g buckwheat flour reproduces the grainy character and slight bitterness of sorghum. Millet flour also works, but the flavor is somewhat different.

This dish contains ingredients that are common allergens. It contains wheat (all-purpose flour), peanuts (peanut butter), buckwheat (listed as a substitute), and milk (yogurt). If you have a wheat allergy, you can leave out the all-purpose flour and make it with only sorghum flour (gluten-free). If you have a peanut allergy, use sesame paste in place of the peanut butter.
Kisra batter needs at least 12 hours of fermentation, and ideally 24. Mixing it the night before and baking it the next day is the most efficient. In winter, when room temperature is low, fermentation slows, so use the oven's proofing function (around 35°C) or a yogurt maker. Adding yogurt makes fermentation start earlier, but without it the batter will still ferment naturally at room temperature.

Tips
Eighty percent of success with kisra is decided in fermentation. The ideal fermentation temperature is 25–35°C. In winter (room temperature 15–20°C) fermentation slows, so secure the temperature in one of these ways: (1) put it in a yogurt maker (the steadiest), (2) set the oven's proofing function to 35°C, (3) lay a damp cloth over the warm mode of a rice cooker to warm it indirectly. In summer, avoid direct sunlight and ferment in a cool, dark place.
Kisra batter is ideally "slightly thicker than coffee cream." When you lift a spoonful and let it fall, it should fall in an unbroken thread. If it is too thick it bakes thick, and if too thin it bakes too thin and tears. Because fermentation adds water, mix the batter "a bit on the thick side" before fermenting.
To bake kisra to an even thinness, the pan temperature must be steady. Over high heat, the batter sets too fast to spread, and over low heat it stays sticky and will not peel. Keep medium-low heat (a drop of water evaporates slowly on the pan). Lifting the pan off the heat for about 10 seconds after each crêpe steadies the temperature.
Kisra on its own is subdued. The sourness of fermentation and the sweetness of the grain are a flavor that is completed only when paired with a fatty, spiced stew (mulah). The oil of the peanuts soaks into the kisra, and the kisra acts as a "vessel" that carries the spice flavor. This relationship parallels that of injera and doro wat.
Variations

Millet kisra
You can make kisra with pearl millet flour instead of sorghum. Use 300 g of millet flour and proceed the same way. It is somewhat sweeter than the sorghum version and the color is a brighter yellow. Millet flour can be found in natural food stores and online.
Wheat-blend version (for beginners)
If you are not set on the authentic flavor, a blend of 150 g all-purpose flour and 150 g sorghum flour is recommended. The gluten in the all-purpose flour acts as a binder and gives a kisra that tears less and is easier to handle. The fermentation time is the same 12–24 hours. If this is your first time making kisra, starting with this blend leads to fewer failures.
Buckwheat kisra (Japanese-style variation)
If you use 300 g buckwheat flour instead of sorghum, the result comes close to a Breton galette (buckwheat crêpe). Buckwheat is also gluten-free and goes well with fermentation, and its distinctive toasty aroma suits the spices of the mulah. Ferment the same 12–24 hours, but buckwheat rises more, so add 50 ml extra water to make the batter looser. As with Indian khichdi, the combination of grain and spice has a universality that crosses borders.
Sweet kisra (dessert version)
Add 2 tbsp sugar and 1 tsp cinnamon to the batter, and sprinkle the baked kisra with honey and ground sesame. It is a dessert version that children also enjoy.
Chicken and vegetable mulah
Use 4 bone-in chicken thighs in place of beef and add 2 eggplants and 1 zucchini. If you brown the surface of the chicken first and then simmer, the gelatin in the skin thickens the soup. It has a lightness like the light soup served with Ghanaian fufu.
Background of the Dish
Sorghum and the civilization of the Nile
Sorghum (Sorghum bicolor), the main ingredient of kisra, is a grain native to northeastern Africa, and archaeological research in eastern Sudan (Winchell et al., 2017) shows that people there used and cultivated sorghum in ancient times.
Sorghum is extremely drought resistant and well adapted to the semi-arid climate of the Nile region. It can be harvested even where wheat and rice will not grow, which is the main reason it has remained the staple in Sudanese cooking.
Fermentation culture and "ajin"
Fermentation is part of everyday food in Sudan, and kisra is at the center of it. Kisra batter is traditionally fermented with a starter culture called "ajin" (ajin / عجين), in which leftover batter from the day before is added to the next batch, a sourdough method. Lactic acid bacteria and yeasts work together in such cultures, giving kisra its flavor and texture.
The idea of this "inheritance of the starter" is close to the house-resident microbes of Japanese miso and soy sauce breweries, and the universal theme of the cultural inheritance of microbes in fermented foods shows through.
The Sudanese table and the culture of shared eating
Sudanese meals center on a large round tray called a "sufra." Kisra is spread on the sufra and the mulah (stew) and salads are arranged on top. Family and guests gather around the sufra and tear the kisra by right hand and dip it in the mulah to eat.
Nutrition (per 3 kisra)
Sorghum is a naturally gluten-free grain.

| Calories | 285 kcal |
| Protein | 8 g |
| Fat | 4 g |
| Carbohydrates | 56 g |
| Fiber | 5 g |

Sorghum is rich in B vitamins (especially B1 and B3) and iron. Combined with the beef and peanuts of the mulah, protein and fat complement each other, making a nutritionally balanced meal.

FAQ
Questions that come up often from people making kisra for the first time, from managing fermentation to storage and substitutes.
Q1. I cannot get sorghum flour. What can I substitute?
The closest substitute is a combination of 200 g whole wheat flour and 100 g buckwheat flour. The whole wheat supplies the grain character and the buckwheat adds its distinctive flavor and color. Millet flour and foxtail millet flour also work, but their flavor alone differs, so blending them half and half with whole wheat is recommended. Fermentation works the same in any case.
Q2. What if fermentation isn't working?
If no bubbles appear after 12 hours, the temperature is most likely too low. Move it to a yogurt maker, or set the bowl of batter in a bowl of lukewarm water (about 35°C) to warm it like a water bath. Stirring in 2 tbsp plain yogurt also speeds fermentation. If it still hasn't fermented after 24 hours, do not throw out the batter; add a small amount of dry yeast (1/4 tsp) and wait 4–6 hours.
Q3. How many days does kisra keep?
Baked kisra, wrapped airtight in plastic wrap, keeps 3 days in the refrigerator. Before eating, microwave for 10 seconds or warm lightly on both sides in a frying pan to restore the softness. It can be frozen for 1 month. Wrap each one in plastic wrap, put them in a zip bag, freeze, and let them thaw naturally before warming to eat.
Q4. Is it safe when kisra is baked on only one side?
Yes. Because kisra batter is thin, the residual heat on one side cooks it all the way through. Heating is sufficient if the surface is completely dry and has a matte texture. If you are concerned, extend the baking by 30 seconds or cover with a lid to steam-bake.
Q5. What is the difference between kisra and injera?
The main differences are ingredients and texture. Kisra uses sorghum flour and is baked into a thin, supple crêpe. Injera uses teff flour and is baked thick and spongy. Kisra is often folded or rolled to eat, while injera is laid under the stew as a plate. The fermentation time is similar, 1–3 days for both, but the grain and the way it is baked differ.
