Here's my contribution to the thread on scalloped potatoes and ham.
As far as I'm concerned, no others need apply. This is the best I've
ever tasted. It's from my new Julia Child book, "The Way to Cook".

Also++since the recipe is for 18 to 24 servings++it'll give the folks
with amountconverting recipe programs a chance to put them through
their paces. ;}

Here is a great crowd pleaser, as well as a deliciously economical
one that needs only a copious salad, a loaf of bread, and a jug of
light red wine to make the meal.

For 18 to 24 servings

SPECIAL EQUIPMENT SUGGESTED:

A food processor is useful for slicing and grating; and 8quart
covered kettle; a heavybottomed 3quart saucepan, for the sauce; a
buttered 6quart baking dish about 3 inches deep, for the final dish

THE POTATOES:

Have ready the kettle containing 4 cups of cold water. Peel the
potatoes and slice them One fourth inch thick, dropping them into the cold
water to cover as you do so. Cover the kettle, and bring to the
boil. Uncover and boil slowly for 3 to 4 minutes, until barely
cooked through++eat several slices to check. Drain, cover the kettle
again for 3 to 4 minutes to firm up the potato slices, then uncover.

THE GARLIC AND MUSTARD SAUCE:

Make the classic white sauce; cook the butter and flour together in
the saucepan until they foam and froth for 2 minutes without
coloring. Off heat pour in half the hot milk; whisk vigorously to
blend as you pour in the rest; simmer for 3 minutes, stirring.
Remove from heat and whisk in the seasonings; bring to the simmer
again; taste carefully, and add additional seasonings to taste. [I
didn't type in the sauce referred to. It was essentially a longer
version of what's given above along with tips on handling it. S.C.]

ASSEMBLING:

Spoon a 1/16inch layer of sauce on the bottom of the buttered baking
dish. Set aside 3 cups of the sauce and 1 cup of the cheese for the
topping. Now, to arrange everything in 4 layers, start with a quart
of the potatoes, then a quarter of the ham, follow by a third of the
sauce and sprinkle on a third of the cheese. Continue in layers,
finishing the final layer with the remaining potatoes and ham; spread
on the reserved 3 cups of sauce to cover completely, then the last of
the cheese.

AHEAD OF TIME NOTE: May be prepared a day in advance, cover when
cool and refrigerate.

An hour or so before you plan to serve, preheat the oven to 375f.

Bake in the upper third level just until the potatoes are bubbling
hot and the top has browned nicely. About 45 minutes.

AHEAD OF TIME NOTE: May be kept warm uncovered on a hot tray but be
sure not to overheat or the potatoes and ham will dry out.
