"Royal fish pie"

The royal seafood tradition of England started in the time of Henry I, crowned in 1100, when cooks rolled crust over an annual Christmas lamprey pie. A separate tradition of Lenten fish pie required Yarmouth cooks to send the king two dozen pies containing 100 herrings.[1] The customary gifts of fish in crust prevailed in 1530, when the prior of Llanthony, Gloucester, baked eels and carp into a pie for Henry VIII. The presentation of the royal eel pie continued in 1752, when bakers sent one to the Prince of Wales, and again during Queen Victoria's reign.[2]"
