- Boldly ignore portion sizes: Overloading the baking dish can lead to uneven cooking. Stick to the recommended amounts of bread and blueberries.
- Boldly forget to adjust sweetness: Each person has different sweetness preferences. Taste the egg mixture before pouring it over the bread and adjust the maple syrup if needed.
