City. For there, instead of the cow, a sort of century plant
gives milky white _pulque_, the fermented juice of this
cactuslike desert plant. With this goes a vegetable cheese curded
by its own vegetable rennet. It's called tuna cheese, made from
the milky juice of the prickly pear that grows on yet another
cactuslike plant of the dry lands. This tuna cheese sometimes
teams up in arid lands with the juicy thick cactus leaf sliced
into a tortilla sandwich. The milky _pulque_ of Xochomilco goes
as well with it as beer with a Swiss cheese sandwich.

Y Yolk Picnic Sandwich

Hard-cooked egg yolk worked into a yellow paste with cream
cheese, mustard, olive oil, lemon juice, celery salt and a touch
of tabasco, spread on thick slices of whole wheat bread.

Z Zebra

Take a tip from Oskar over in Copenhagen and design your own
Zebra sandwich as decoratively as one of those oft-photoed skins
in El Morocco. Just alternate stripes of black bread with various
white cheeses in between, to follow, the black and white zebra
pattern.

For good measure we will toss in a couple of toasted cheese
sandwiches.

Toasted Cheese Sandwich

Butter both sides of 2 thick slices of white bread and sandwich
between them a seasoned mixture of shredded sharp cheese, egg
yolk, mustard and chopped chives, together with stiffly beaten
egg white folded in last to make a light filling. Fry the
buttered sandwich in more butter until well melted and nicely
gilded.

This toasted cheeser is so good it's positively sinful. The French,
who outdo us in both cooking and sin, make one of their own in the
form of fried fingers of stale bread doused in an 'arf and 'arf Welsh
Rabbit and Fondue melting of Gruyere, that serves as a liaison to
further sandwich the two.

Garlic is often used in place of chopped chives, and in contrast to
this wild one there's a mild one made of Dutch cream cheese by the
equally Dutch Pennsylvanians.

England, of course, together with Wales, holds all-time honors with
such celebrated regional "toasting cheeses" as Devonshire and Dunlop.
Even British Newfoundland is known for its simple version, that's
quite as pleasing as its rich Prince Edward Island Oyster Stew.
