Use sturdy, thick bread to absorb the custard without getting soggy. Pieces of French bread, challah, or brioche would be a good choice.
To make sure the bread absorbs all of the flavors, let it soak in the custard mixture for at least one minute on each side.
To give the toast a deep, fragrant taste, add nutmeg, cinnamon, and vanilla essence to the custard.
For a golden, crispy crust and an extra layer of richness, fry the bread in butter.
To make it dessert-worthy, add garnishes like melted chocolate, toasted almonds, or fresh berries.
