In a small bowl, combine the raisins with ron. Cover and soak for 1 to 2 hours.
1 cup raisins, ¼ cup ron
In a large mixing bowl, combine half of the milk and cubed bread. Use your hands to press the bread into the milk until fully saturated (it may not absorb all the milk).
2 cups milk, 6 cups French bread
In a separate bowl, whisk the egg, then add the sugar, vanilla, nutmeg, and cinnamon. Add the rest of the milk, mix well and pour this mixture over the soaked bread and add the ron-soaked raisins. Stir gently to combine.
1 large egg, 1 cup sugar, 1 tablespoon vanilla extract, ½ teaspoon cinnamon, ¾ cup milk, ¼ teaspoon nutmeg
Lightly grease a 9x13 inch baking pan.
Pour the bread mixture into the prepared pan. Bake in the air fryer at 160ºC (320°F) for 25 minutes, or until the edges are slightly browned and pulled away from the sides of the pan.
Serve with the English cream.
