For Christmas morning, I made brioche custard french toast. Even though I am Jewish, one of my fathers still has us celebrate Christmas. I have made this recipe one time before, but we used french bread instead. This dish turned out amazing. The brioche was better than the french bread. I started out two days in advance leaving out the bread so it would get stale. The bread must be stale enough so that it does not disintegrate when it is soaking overnight. The bread did not get as stale as I wanted, so I put it in the oven for a bit to dry it out more. In the end, the french toast was still not as crispy as I would have liked. But it was so incredibly flavorful. The secret ingredients that the bread soaks in overnight are orange zest and Grand Marnier.
