Hi Christofer.
Welcome to the Scoolinary community! Thank you for your question.
The difference between brushing with egg and milk vs. yolk with a bit of water lies in the final baked appearance:
1. Whole egg + milk:
Provides a moderate shine and a uniform golden color.
The milk gives a slightly softer and more matte tone compared to using only egg.
Commonly used for croissants, brioche, and burger buns when a glossy but not overly intense finish is desired.
2. Egg yolk + a bit of water:
Creates a more intense and deep color, with a shinier finish.
The yolk contains more fat, which enhances browning and richness in appearance.
Ideal for brioche if you want a more vibrant and attractive color.
Which is better for brioche and maritozzi?
For brioche and maritozzi, the best choice depends on the finish you prefer:
If you want a more intense and glossy color, use yolk with a bit of water.
If you prefer a softer and more uniform finish, choose whole egg with milk.
For a more classic and professional look in brioche and maritozzi, the most common option is yolk with a bit of water, as it enhances the bread’s color and appearance.
Let me know which option you prefer for glazing your breads!
Best regards.
