First, choose an egg-y and rich bread, like challah or brioche, and cut it into thick slices. Next, create a custard with the correct ratio of milk to eggs. In general, you want to use 1 cup of milk for every 4-5 eggs. You should only soak it for 1 minute to avoid soggy French toast. Finally, cook French toast over medium heat for 3-4 minutes, until golden brown on the outside and the custard is set.
