Recipe: Tart of Salmon & Greens (c.1390)

From King Richard II's cookery book, I've adapted a GLUTEN FREE version of the delicious Crustarde of Erbes on a Fysche Day, eaten on so-called 'fish days' (medieval fasting days, i.e., Wednesdays, Fridays and Saturdays). The recipe includes my edition and translation of the original recipe.
