French toast is a dish of sliced bread soaked in beaten eggs and often milk or cream, then pan fried. Alternative names and variants include "eggy bread", "Bombay toast", "gypsy toast", and "poor knights" (of Windsor).
When French toast is served as a sweet dish, sugar, vanilla, or cinnamon are also commonly added before pan-frying, and then it may be topped with sugar (often powdered sugar), butter, fruit, or syrup. When it is a savory dish, it is generally fried with a pinch of salt or pepper, and it can then be served with a sauce such as ketchup or mayonnaise.

The recipe says to "Break [slice] fine white bread, crust removed, into rather large pieces which soak in milk [and beaten eggs] fry in oil, cover with honey and serve".

Day-old bread is often used, both for its thrift and because it will soak up more egg mixture without falling apart.
The cooked slices may be served with sugar or sweet toppings such as caramel, ice cream, jam, honey, fruit, and/or maple syrup.
