Tomorrow's French Toast
Lightly brush an 8-inch square glass baking dish with butter. Brush the remaining butter on both sides of each slice of bread and lay the slices in the prepared pan.
In the same bowl, beat together the egg, milk, cinnamon and salt with a fork and then pour over the bread. Cover with plastic wrap and chill overnight. In the morning, place the pan in the oven at 425°. Set the timer for 15 minutes and bake until the toast is puffed and golden, up to 18 minutes total. Loosen the French toast slices with a flexible metal spatula and serve.
Note: Adding salt heightens the flavor of any sweet or savory dish. We like kosher salt for its pure salt flavor, but in baking we always use fine table salt.
