Substitutions

  • Caraway → Dilladmissible

    Both are traditional optional aromatics

  • Cultured sour cream → Fresh sweet creaminadmissible

    Without the cultured tang it is just whipped butter, not kastinys

  • Dairy → Plant cream/butterinadmissible

    Kastinys is fundamentally a cultured-dairy product; a vegan version is a different food

Common mistakes

  • Using sweet cream instead of cultured sour cream, losing the defining tang
  • Letting the mixture split by overheating the butter
  • Treating it as a sauce rather than a thick spreadable condiment

Provenance

An old peasant condiment of the Samogitia (Žemaitija) region of northwestern Lithuania, historically a way to enrich plain potatoes; now a heritage Lithuanian specialty.
