Fischgericht der Festtage (the fish dish for feast days and fast days)

Karpfen blau — blue carp in vinegar court-bouillon with spiced sauce

FestiveReconstruction🍋 🧂moyen1 h

A whole carp gently poached in a vinegar court-bouillon that tints its skin a bluish hue, served warm with a medieval sauce of gingerbread, ginger, and clove, sweet-and-sour and fragrant. A prestige dish to share.

Why this dish? "The typical meal included... fish." Carp, raised in the ponds of monasteries and manors in Saxony, was THE festive and fast-day fish in Luther's Germany. Served "blue" in vinegar, it adorned wedding tables — like those that followed the marriage of the defrocked monk to Katharina in 1525.
For a feast day, have a fine carp brought from the pond, still frisky! Place it alive in the vinegar broth, and behold, it adorns itself in a blue like the cloak of heaven — God slips his wonders even into our bowls. Käthe serves it with a sauce where ginger and clove sing, neither too sweet nor too sour, as a good doctrine should be. It is wedding meat and joyful table fare: give thanks, and keep some for the poor at the door.

How it was made : Monastic fish farming provided carp and tench for the many "lean" days of the Christian calendar. Late medieval and German Renaissance cuisine loved sweet-and-sour sauces thickened with gingerbread and loaded with imported spices (ginger, clove, pepper) — a marker of prestige. "Karpfen blau" remains a Christmas and New Year classic in Germany.
