Monte Cristo Sandwich From Mama'S - cooking recipe

Ingredients

8 slices white bread
mayonnaise, as needed
4 slices gouda cheese
ham steak, cut up and pan-fried
3 large eggs, beaten
1/4 cup milk
2 tablespoons vegetable oil
1 tablespoon unsalted butter
powdered sugar
blackberry jam

Preparation

On a work surface, spread each slice of bread with mayonnaise. Top four slices with the 1 slice of Gouda and several pieces of fried ham steak. Use remaining slices to top ham and cheese slices to make four sandwiches.
Using a knife, cut the crusts off the sandwich (this helps to pinch and seal the ends). Press sandwich flat with hands and wrap tightly with plastic wrap.
Refrigerate for at least 30 minutes and up to 6 hours. (Wrapping the sandwich in plastic wrap, compacts it, and prevents the egg batter from seeping in.).
Heat the oil and butter in a skillet over medium-high heat.
Combine the eggs and milk in a bowl.
Unwrap the sandwiches and dip them in the egg batter, to coat evenly.
Gently place each sandwich in the skillet (one or two at a time), and fry, turning once, until golden brown and hot, about 5 minutes total.
Cut the Monte Cristos in 1/2, transfer to a place, and sprinkle with powdered sugar.
Spoon some jam on the side and serve immediately.
