Fasts

old and sick needed meat to remain strong. Many monks just went to the
infi rmary for supper.
The main substitute for meat on a fast day was fi sh. Medieval kitchens
dealt with a wide range of fi sh, both freshwater and saltwater. Recipe books
specifi cally mention herring, pike, bass, salmon, carp, cod, trout, perch,
tench, bream, haddock, whiting, whale, dogfi sh, mackerel, fl ounder, sole,
skate, cuttlefi sh, crayfi sh, porpoise, seal, lamprey, eel, oysters, lobster, crab,
mussels, and more. Modern classifi cation does not include seal, whale, or
porpoise as fi sh, since they are mammals, and, of course, shellfi sh are their
own class. But to a medieval cook, if it came from the water, it was a fi sh.
Beaver and otter were classed as fi sh for a time, and the tail of the beaver
continued to be permitted as fi sh. There were even fi sh that did not come
from water, such as newborn rabbits. Finally, legend told that the barnacle
goose, a migrating bird, was born from barnacles at sea and that it was a
sort of fi sh appropriate for fast days.
Recipes normally made with meat were stuffed with fi sh or nuts dur-
ing fast seasons. By the 12th and 13th centuries, cooks at large monaster-
ies, manors, and castles could prepare fi sh, eels, and shellfi sh in so many
ways that the table did not suffer at all in variety. Fish could not make up
all defi cits; recipes that called for milk or butter needed other substitutes.
Almond milk worked in most recipes; the nut was ground fi ne and mixed
with water, and its natural oils and nut meat formed a thickened white liq-
uid that cooked up somewhat like milk.
Large parts of Northern Europe depended on butter as a main cooking
fat. The alternative was meat fat, which was also forbidden, so it became
diffi cult to cook. In regions that depended on walnut or olive oil, this was
not a problem. During the later Middle Ages, the Pope began to permit
regions to purchase permission to use butter on fast days. The money often
went toward building projects, like cathedrals. Cheese was the other major
milk product; during Lent, dairies continued to make and age cheese, but
nobody was allowed to taste it.
A cook’s most serious problem with creating palatable dishes with fi sh
was the tasteless nature of most preserved fi sh. While aristocratic tables
could serve fresh carp, eel stews, or salmon, most people made do with
stockfi sh and pickled herring. Stockfi sh had to be pounded and soaked
and could not be made into anything more interesting than fi sh stew or
fi sh pie. Cod or herring preserved with salt made people very thirsty, and
Lent was often a time of greater drunkenness as diners tried to wash down
the salt with ale. Cooks rinsed and soaked salted fi sh repeatedly, and they
used spiced sauces to cover the taste. Good cooks could do well even with
salted, dried fi sh. A well-funded monastery could dine on roasted carp, her-
ring soup in almond milk, spiced cod pies, and a variety of alcoholic drinks
(from wine to cider to berry wines) to wash down the lingering salt.
