Ingredients
4 large eggs
1/4 cup heavy cream
2 teaspoons sugar
1/2 teaspoon salt
1/2 teaspoon dry mustard
1/8 teaspoon cayenne pepper
6 tablespoons strawberry or raspberry jam
2 tablespoons Dijon mustard
12 slices hearty white sandwich bread, lightly toasted
18 thin slices deli Swiss or Gruyère cheese
12 thin slices deli ham, preferably Black Forest
12 thin slices deli turkey
3 tablespoons vegetable oil
Confectioners’ sugar
Preparation
Adjust an oven rack to the upper middle position and heat the oven to 450°F. Whisk the eggs, cream, sugar, salt, dry mustard, and cayenne in a shallow dish until combined. Stir the jam and Dijon mustard together in a small bowl.
Spread 1 teaspoon of the jam mixture on one side of each slice of toast. Layer the slices of cheese, ham, and turkey on 6 slices of toast. Repeat with a second layer of cheese, ham, and turkey. Add a final layer of cheese and top with the remaining toast, with the jam side facing the cheese. Using your hands, lightly press down on the sandwiches.
Pour the oil onto a rimmed baking sheet and heat in the oven until just smoking, about 7 minutes. Meanwhile, using two hands, coat each sandwich with the egg mixture and transfer to a large plate. Transfer the sandwiches to the preheated baking sheet and bake until golden brown on both sides, 4 to 5 minutes per side, using a spatula to flip. Sprinkle with confectioners’ sugar and serve immediately with the remaining jam mixture.
