作法
- 厚底鍋將牛奶加熱至 80°C—接近沸點但未沸騰。維持 5 分鐘以殺死雜菌。
- 降溫至 45°C—溫度對優格菌活性至關重要。請使用溫度計；摸起來溫暖但不燙。
- 拌入優格菌種，倒入乾淨的瓶子或加蓋陶罐中。
- 置於溫暖處（28 至 30°C）8 至 12 小時，期間不要動。優格會凝固。蒙古家庭會用毯子包裹陶罐保溫。
- 上桌前至少冷藏 4 小時，Tarag 即可享用。
- 上桌時：徹底攪拌均勻。加入鹽或糖（不同家庭偏好不同版本）。可加冷水稀釋成較稀薄的飲品。倒入高杯加入冰塊冷飲，可以蒔蘿或薄荷裝飾。

文化背景
蒙古優格飲是當地的優格飲品—家庭常備品，尤其在夏季。鹹味版較傳統，是蒙古獨有的風味；甜味版則是蘇聯時期出現的，現今在烏蘭巴托較常見。蒙古孩子從小喝著優格飲長大；年長一輩偏愛加一撮蒔蘿的鹹味版。這道飲品的目的是解渴與補水，特別在吃過油膩的羊肉大餐之後。每戶蒙古家庭都有偏好的菌種，有時是世代相傳。
