Ingredients

10 lb
potatoes
"just a pinch" of salt
garlic and mustard sauce
5 oz
butter
1 c
all purpose flour
6.5 c
milk, heated
"just a pinch" of salt
"just a pinch" of pepper
"just a pinch" of nutmeg
2
garlic clove, pureed
1/4 c
dijon mustard
1/2 tsp
thyme
4 c
cheese, grated
1.5 qt
ham, cooked and thinly sliced

Directions Step-By-Step

1
THE POTATOES: Have ready the kettle containing 4 cups of cold water.
2
Peel the potatoes and slice them 1/4 inch thick, dropping them into the cold water to cover as you do so. Cover the kettle, and bring to the boil.
3
Uncover and boil slowly for 3 to 4 minutes, until barely cooked through and eat several slices to check.
4
Drain, cover the kettle again for 3 to 4 minutes to firm up the potato slices, then uncover.
5
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.
6
Turn off heat and pour in half the hot milk.
7
Whisk vigorously to blend as you pour in the rest.
8
Simmer for 3 minutes, stirring.
9
Remove from heat and whisk in the seasonings.
10
Bring to the simmer again.
11
Taste carefully, and add additional seasonings to taste.
12
ASSEMBLING: Spoon a 1/16-inch layer of sauce on the bottom of the buttered baking dish.
13
Set aside 3 cups of the sauce and 1 cup of the cheese for the topping.
14
(Swiss or a mixture such as swiss, mozzarella, jack, and/or cheddar.)
15
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.
16
Continue in layers, finishing the final layer with the remaining potatoes and ham.
17
Spread on the reserved 3 cups of sauce to cover completely, then the last of the cheese.
18
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.
