Skimmed cow's milkessentialLow-fat milk left after cream is removed for butter

Acid

Lactic acid / souringessentialAcidification curdles the milk and defines the sharp taste

Seasoning

SaltessentialFor seasoning and preservation

Caraway or pepperoptionalSome versions are spiced when served

Technique

Acid coagulation of skimmed milk
Souring rather than rennet sets the curd and creates the cheese's signature tang and lean body
Low-fat milk base
Using skimmed milk yields the characteristically lean, firm, sour cheese distinct from rich Alpine wheels
Maturing
Aging intensifies the sharpness and can turn the paste translucent

Substitutions

  • Caraway seasoning → Black pepper or plainadmissible

    Flavoring is regional preference

  • Hand-soured curd → Cultured lean curdadmissible

    Modern dairies use starter cultures with similar result

  • Skimmed milk → Whole or rich milkinadmissible

    Makes a fatty cheese, no longer the lean sour cheese it is defined as

  • Acid coagulation → Rennet-set curdinadmissible

    A rennet cheese is a different category entirely

Common mistakes

  • Treating it as a rich, creamy cheese — it is defined by being lean and low-fat
  • Assuming rennet sets the curd rather than acidification
  • Confusing it with sauerkraut due to the name
  • Expecting a mild flavor — its hallmark is sharp sourness

Provenance

A traditional lean acid-curd cheese of Liechtenstein and the wider eastern Alpine region, historically made to use the milk left after cream was skimmed for butter.
