This is a delicious marinated and pickled salad, and tastes nothing like the images the name suggests! The modern recipe is a modified (but just as tasty) version of the medieval receipt, containing only the "pasternak" (carrots - from the Latin "pastinaca"), "caboches" (cabbage), "raisons of coraunce" (currants), and "peeres" (pears). The other medieval ingredients are "rote of persel" (parsley root), "rafens" (radishes), and "rapes" (white turnip).
"Lumbarde" (or "Lumbard") mustard was a mixture of ground mustard seed mixed with honey, wine, & vinegar. "Pouder douce" was a mild concoction of ground spices, often containing sugar, though not always; in general, pouder douce usually included cinnamon but not pepper.
