作法
- 厚底鍋中將牛奶加熱至 35°C—僅微溫不熱。緩慢加熱很關鍵；溫度劇變會破壞蛋白質。
- 加入凝乳酶（或檸檬汁）。輕輕攪拌 30 秒，靜置 60 分鐘不要動。牛奶會凝結成扎實凝乳。
- 用長刀將凝乳切成 1 公分小方塊，靜置 10 分鐘讓乳清釋出。
- 緩慢加熱凝乳乳清混合物至 38°C，輕輕攪拌。凝乳會結實。倒入鋪有紗布的篩網中瀝乾，乳清可保留作其他用途。
- 瀝乾的凝乳放入木模壓製 4 至 6 小時，乳酪會壓縮成扎實淡色的塊狀。
- 表面豪邁地撒上鹽。有些版本會加葛縷子籽。用紗布包好冷藏至少 24 小時。乳酪即可切片享用。搭配麵包、果乾與奶茶食用。

文化背景
蒙古鮮乳酪反映了當地的鮮乳酪傳統—每戶游牧家庭都會在牲畜產乳量最豐的夏季製作。乳酪冷藏可保存數週，傳統上會進一步乾燥成 Aaruul（更硬、徹底乾燥的乾酪），供冬天食用。在杭愛山等高海拔地區可見犛牛奶版本，草原上則以牛奶版較普遍。現代蒙古超市販售大量生產的工廠版，但牧民自製的版本風味明顯不同。
