Substitutions

  • cognac → brandy or other grape spiritadmissible

    A near-equivalent that keeps the character

  • cognac → no alcoholinadmissible

    Without spirit it is just egg custard, not a liqueur

  • egg yolks → whole eggs or substituteinadmissible

    Yolks are essential to the rich body; whites or substitutes break the texture

Common mistakes

  • Overheating and curdling the yolks into scrambled bits
  • Under-sweetening so the raw-egg note dominates
  • Using a harsh spirit instead of smooth cognac/brandy
  • Failing to emulsify, leaving it thin and separated

Provenance

A settled Luxembourgish homemade egg liqueur in the same family as Dutch advocaat and German Eierlikör, traditionally made for festive occasions.
