Regional variations

  • Restaurant mast-o-musir · Iran

    Often served free as an appetiser dip with bread or chips

  • Homemade with fresh musir · Zagros regions

    Made with fresh wild shallots where available

Related dishes

  • sibling Tzatziki

    Both are cooling yogurt dips, but flavoured differently

  • pairs-with Chelo kabab

    Served alongside Iranian grilled meats

Substitutions

  • Dried musir → Fresh musir / wild Persian shallotadmissible

    Fresh is the original; both give the right flavour

  • Strained yogurt → Plain thick yogurt drained brieflyadmissible

    Acceptable if no labneh-style yogurt available

  • Musir → Ordinary onion or garlicinadmissible

    Loses the distinctive mild wild-shallot flavour that names the dish

Common mistakes

  • Using raw, un-soaked musir so the dip is harshly pungent
  • Substituting ordinary onion and losing the wild-shallot character
  • Using thin, runny yogurt instead of strained
  • Over-salting a condiment meant to be gently seasoned

Provenance

A classic Iranian table condiment built around musir, the wild shallot foraged and dried across the Iranian plateau.
