5 (3/4-inch-thick) slices from an unsliced loaf of firm white sandwich bread or challah
1 cup heavy cream
4 large eggs, lightly beaten
1/4 teaspoon salt
About 4 cups vegetable oil for frying
Confectioners sugar for dusting
Accompaniment: warm maple syrup or honey
Special equipment: a deep-fat thermometer
Directions
Preheat oven to 400°F.
Cut off and discard crusts from bread, then diagonally halve slices. Arrange in 1 layer in a baking pan.
Whisk together cream, eggs, and salt, then pour over bread. Soak bread, turning once, until most of liquid is absorbed but bread is not falling apart, about 2 minutes.
Carefully transfer soaked bread with a slotted spatula to a tray.
Heat 1/2 inch oil in a 12-inch heavy skillet over moderate heat until thermometer registers 325°F.
Fry bread, 3 pieces at a time, turning over once, until golden brown and crisp, about 2 minutes. (Return oil to 325°F between batches.) Transfer toast to paper towels to drain briefly, then arrange in 1 layer on a baking sheet.
Once all bread is fried, bake toast in middle of oven until puffed, about 4 minutes. Serve dusted with confectioners sugar.
