PRACTICAL WALKTHROUGH · PARAMETERS · COMMON MISTAKES
Mongolian air‑drying of yak cheese, known as aaruul, involves exposing curd to ambient conditions (20–30 °C, 30–50 % RH) for 7–10 days, during which moisture loss, proteolysis, and lipid oxidation drive flavor development while preventing spoilage.
Origin: Mongolian nomads (Traditional) — Mongolia
See full technique reference →During drying, water evaporates from the curd, lowering moisture from ~70 % to <10 %. Proteolytic enzymes continue to cleave casein and whey proteins, generating free amino acids and peptides that contribute to the characteristic nutty and tangy flavor. Concurrently, lipids undergo oxidation, producing volatile aldehydes that add depth to the aroma profile.
