Monte Cristo Sandwich is piled high with ham, turkey, cheese, and three slices of honey wheat bread that is dipped in batter and deep-fried to a golden brown.
After chilling the sandwiches, make the batter*.
In a large bowl combine flour, baking powder, and salt. Whisk to combine.
In a separate bowl combine water and egg, whisking to combine. Pour the wet mixture into the dry mixture and whisk well until all ingredients are incorporated and the batter is smooth. Set aside while you heat the oil.
Pour about 2 inches (or more) of oil into a large pot (enough to cover the sandwich) and set it over medium heat. Heat the oil to a temperature between 325°F-350°F.
Working one half a sandwich at a time, remove the plastic wrap from the chilled sandwich and dip it into the batter with your hands. Then, use metal tongs to dip the sandwich into the hot oil. You may have to hold down the sandwich to submerge in oil or flip it. Fry until golden brown (4-5 minutes with homemade batter or closer to 4 minutes with pancake batter ). Remove from the oil and set on a paper towel-lined plate to drain slightly. Repeat with the remaining halves.
Sprinkle the fried sandwich lightly with confectioners' sugar and serve with a side of raspberry preserves for dipping.
*You can also storebought pancake batter, like Krusteaz (the brand we tested). The different batters can result in a sweeter, thicker, or crispier sandwich.
