Substitutions

  • Smoked fish → Beef or goatadmissible

    Protein choice is flexible across households

  • Waterleaf → Spinachadmissible

    A common stand-in for the tender greens component

  • Gnetum leaves → Spinach or collards aloneinadmissible

    Substituting away the gnetum entirely removes the dish's defining leaf and identity

  • Red palm oil → Neutral vegetable oilinadmissible

    Loses the color, flavor and richness central to the dish

Common mistakes

  • Not shredding the tough leaves finely enough, leaving them chewy
  • Skimping on palm oil, losing the dish's richness and color
  • Omitting crayfish, flattening the umami base
  • Substituting gnetum entirely with ordinary spinach, which changes the dish
