If you want to make a dark egg wash, use just the yolk and a pinch of salt. The salt will liquefy the yolk so it’s easier to spread.
Keep in mind that each liquid will give you a different look. For example, water will give a matte appearance while milk and cream give shine.
Avoid whisking the egg wash until the egg foams.
Keep in mind that the heavy cream is more likely to crack as it expands.
For another vegan egg wash, mix a few teaspoons of water with soy powder.
If a lot of egg wash puddles near the bottom of the bread, you’ll have bits of cooked egg stuck to the loaf.
If you’d like the pastry to be pale and crisp, consider making an egg wash with just the egg white and water.

For example, brush a pie with egg wash and sprinkle coarse sugar on top. If you’re baking bread, scatter sesame or poppy seeds over the wash. If you want to lay decorative pastry pieces on top of pastry, brush a little egg wash on the decorations before setting them in place.
