Sudan's braided cheese, a semi-hard stretched-curd cow cheese flavoured with black cumin. The curd is soured until a test piece stretches into a long rope in hot water, then kneaded in hot water or whey, drawn into ropes, braided and kept in salted whey. It is the country's second most eaten cheese after the white gibna bayda.
Amounts from a sourceRecipes of two university studies in Sudan; Altahir et al. also added calcium chloride. Sudan makes about 7,500 tons a year in small businesses.

Sudan's braided cheese, a semi-hard stretched-curd cow cheese flavoured with black cumin. The curd is soured until a test piece stretches into a long rope in hot water, then kneaded in hot water or whey, drawn into ropes, braided and kept in salted whey. It is the country's second most eaten cheese after the white gibna bayda. Made in 6 steps over 14 h. The longest step, keep in salted whey, takes 12 h (El Gabali TMMA 2023) and runs at 4 °C (El Gabali TMMA 2023). Salt is 3 % (El Gabali TMMA 2023). Starter of Lactobacillus delbrueckii subsp. bulgaricus and Streptococcus thermophilus, which sours the curd until it stretches does most of the fermenting.
In the study recipes the braids were kept in salted whey at 4 °C or 5 ± 2 °C. Proteolysis and pH changed more during storage in raw-milk cheese than in cheese from pasteurised milk. In a survey of 54 braided cheeses sold in Khartoum, 89 % had total viable counts of log 7.5–9.5 cfu/g and 89 % had coliform counts of log 2.0–2.80 cfu/g, and the authors call the samples highly contaminated. Some braids are made from raw milk. CDC says raw milk can carry Campylobacter, Cryptosporidium, E. coli, Listeria, Brucella and Salmonella. It says children under 5, adults over 65, pregnant women and people with weak immunity are at higher risk of serious illness.
Hazards the sources name: Coliform bacteria (log 2.0–2.80 cfu/g in 89 % of 54 braided cheeses sold in the Khartoum market; the authors call the samples highly contaminated).
