1. Preheat the oven to 180°C. Line a baking tray with parchment paper.

2. In a shallow bowl, whisk the egg and egg whites until foamy. Whisk in the milk, rosewater, and cinnamon.

3. Dip bread slices two at a time in the mixture for 1 minute on each side until well soaked. Hold over a dish to drain off excess liquid.

4. In a large frying pan over a medium heat, heat 1 tablespoon of butter.

5. Add soaked bread slices one at a time and cook for 1 to 2 minutes on each side until golden.

6. As soon as a bread slice is done, place it on the baking tray and keep warm in the oven.

7. To serve, top the warm French toast with berries of your choice and a drizzle of maple syrup.
