Best Monte Cristo Sandwich - cooking recipe

Ingredients

8 slices firm bread (we use pepperidge farm)
8 slices deli ham
8 slices deli turkey
4 slices American cheese (or you can use cheddar, my kids prefer american)
4 slices swiss cheese
Coating mixture
1 egg, beaten
1/2 cup water
1/2 cup milk
1/2 teaspoon salt
1 tablespoon sugar
2/3 cup flour
1 3/4 teaspoons baking powder
2 teaspoons honey dijon mustard
powdered sugar, garnish
maple syrup or jam, for dipping
oil (for frying)

Preparation

Assemble four sandwiches using bread, meats, and cheeses. Set aside. In medium mixing bowl (I use a square casserole dish), combine egg, water, milk, salt, sugar, flour, baking powder & mustard. Beat well. Heat about 1\" of oil in deep skillet (I use a large iron skillet). Dip your sandwiches into the coating mixture, I like to get them well soaked. They will be drippy -- try to drain off a bit, carefully slide into the hot oil. Repeat with remaining sandwiches. When nicely browned, gently flip over & brown other side. Remove to paper towels. Sprinkle with powdered sugar. Let cool a few minutes before cutting so the cheese doesn't ooze out. Cut each sandwich into four fingers for easy dipping. Serve with syrup or jam.
