作法
- 厚底鍋中將牛奶加熱至 35°C。加入凝乳酶（或檸檬汁），輕輕攪拌靜置 60 分鐘讓凝乳成型。
- 凝乳切成 1 公分小方塊，靜置 10 分鐘。
- 緩慢加熱至 38°C，輕輕攪拌—凝乳會變結實。倒入紗布瀝乾，乳清可保留。
- 凝乳壓製 30 分鐘以擠出更多乳清。拌入鹽（如要做甜味版則加糖）。
- 將凝乳塑成各式小造型—蒙古乾酪有數十種樣式：小球、扁長方塊、結節、扭結等，是各區域傳統造型。
- 排放於晾曬架上，置於陽光直射處 5 至 7 天，每天翻面一次（食譜列出的烹調時間僅為動手時間）。乾酪會徹底硬化。裝入棉布袋常溫保存可放數月。

文化背景
蒙古乾酪反映了當地的酪保存傳統—每戶游牧家庭都會在夏季產乳期製作乾酪，供冬季食用。這道食物與旅行、儲藏密不可分；乾酪可塞進馬鞍袋、保存數月，提供蛋白質與鈣質。各地造型不同：哈拉哈（中部蒙古）做圓形乾酪；西部蒙古（衛拉特）做扁厚長方形；游牧牧民會手捏成結節狀。蒙古孩子從小含著乾酪長大—它承載了童年的鄉愁。
