Mastering Pastry Washes
A pastry wash is a thin coating applied to dough before baking to control color, shine, and texture. By choosing the right liquid, you determine whether the final result is matte, golden-brown, or deep, polished mahogany.
Consistency is your primary tool.
Always strain your wash through a fine-mesh sieve to remove chalazae or clumps; a smooth liquid ensures an even, streak-free surface.

What goes in.
- 1large egg
- 1 tbspliquid (water, milk, or cream)
- pinchfine salt
Avoid pooling in the valleys
Excess wash settling in the seams of a braid or the base of a pie crust prevents the dough from rising correctly and creates leathery patches. Wipe your brush against the side of the bowl until it is damp, not dripping.
The method.
Combine
Whisk the egg and your chosen liquid together in a small bowl until the whites are fully broken down.
Strain
Pour the mixture through a fine-mesh sieve into a clean container to ensure no bits of egg white remain.
Apply
Use a light, sweeping motion with your brush. Cover the dough surface completely, but do not let the wash run off the sides.
Optional second coat
For a deep, uniform color, let the first coat dry for 5 minutes, then apply a second layer before putting the tray in the oven.
Other turns to take.
Egg Yolk and Cream
Produces a dark, high-shine, mahogany finish for enriched doughs like brioche.
Whole Milk or Cream
Results in a matte, light-brown finish, ideal for biscuits or scones where you do not want a sticky exterior.
Egg White and Water
Provides a subtle sheen without adding significant color, useful for delicate pastries.
When it doesn't go to plan.
Use a natural-bristle brush for intricate designs, but a silicone brush is easier to sanitize.
Chill your shaped pastry in the refrigerator for 10 minutes after applying the wash; this sets the liquid and prevents it from running during the initial bake.
If you are sprinkling sugar or seeds on top, apply them immediately after brushing while the wash is still wet.

Why does my pastry wash leave streaks?
You are likely using too much liquid. The wash should be a thin, transparent film, not a puddle.
Can I make a wash without eggs?
Yes, brush with warm milk or a light agave syrup diluted with water to encourage browning.
