Substitutions

  • Local fresh cheese → Another mild melting cheeseadmissible

    Works as long as it melts into the cassava

  • Cassava → Potatoinadmissible

    Loses the distinctive yuca character; becomes a different patty

  • Cheese → No cheeseinadmissible

    The cheese is integral; without it the dish is plain cassava, not sonso

Common mistakes

  • Using potato instead of cassava, losing the defining yuca texture
  • Skipping the cheese, which is essential to the dish
  • Under-grilling so the outside never crisps

Provenance

A specialty of the eastern Bolivian lowlands around Santa Cruz, where cassava and fresh cheese are staples.
