An egg wash in cooking is a liquid mixture based on raw egg used to brown pies, etc. You vary the mixture easily to achieve exactly the effect you want.

How to make an egg wash

First, a summary of the principles. Sometimes you may use the whole egg, just the yolk, or just the white (the egg is usually chicken egg.) The more yolk, the darker the finish on a baked good. The liquid is usually milk or water. The less liquid, the crisper the finish on a baked good. Salt in an egg wash helps break down the protein in the eggs, helping crumb coatings, etc, stick better to the wash. Ground spices such as cinnamon or nutmeg adds surface flavouring and a bit of colouring.

Egg wash recipes



Desired Effect / Use
Ingredients
Shiny surface
1 whole egg, few dashes of salt
Faint shine
1 whole egg, 1 teaspoon to 3 teaspoons of milk
Matte, golden-brown surface
1 whole egg, 1 teaspoon to 3 teaspoons of water
Shiny, golden-brown surface
1 egg yolk, 1 teaspoon to 3 teaspoons of water
Shiny, darker surface
1 egg yolk, 1 teaspoon to 3 teaspoons of cream
Shiny, golden-brown surface
1 egg yolk, few dashes of salt
Matte, golden-brown surface
1 egg white, few dashes of salt
Crispy, paler surface
1 egg white on its own, lightly beaten
Binder for a coating
1 whole egg, few dashes of salt

Generally, a 1-egg mixture is enough for most applications (such as a pie) unless you are batch cooking or dipping many items in a coating. In which case, double or triple the ingredients in the above table.

Directions

  • first crack the egg in a medium-sized dish or measuring jug, and beat it with a whisk to blend;
  • add about 1 teaspoon to 3 teaspoons of liquid per egg (or egg yolk, or egg white);
  • add any additional items (salt, cinnamon, nutmeg) and whisk well (but don't froth it);
  • thin the wash out a bit further with more liquid if it looks like you need just a bit more.

Egg wash uses

Understanding the different types of effects you can achieve with an egg wash helps you pick the right ingredients for it.


Egg wash as a surface browner


When used to finish the surface of something, the mixture is brushed on ("washed on" if you will, hence the name) prior to its being baked, usually an item with a crust such as pies, bread rolls, breads, Cornish pasties, empanadas, etc.

Egg wash as a binder


When used as a binder, an egg wash can help the coating of food being dredged (in flour, for instance) to stick on better. You wash and dry and pieces of meat or fish, dip them in the egg wash, then dredge them in the coating material. Sometimes an item such as a pie or a bread may have you place a bit of decoratively-shaped dough on top. Brushing the surface first with egg wash before applying the decorative bit helps the decorative bit to stay attached. You then brush the decorative bit as well to ensure that it has the same colour as the rest of the surface.

Egg wash as a sealer


An egg wash can also "seal" the surface of a food item. Some recipes will have you brush the surface of a pastry shell being baked "blind" with egg wash, in order to seal the surface against moisture from the anticipated filling.

Industrial eggwashes

Commercial bakers often use an artificial egg wash, sprayed on baked goods before baking as they pass through special applicator machines.

Industrially, an "egg wash powder" is available, but that's a different item altogether -- it's used to actually wash the shells of fresh, whole eggs straight from the farm. It's used in the ratio of 1/10 to 1/2 oz per gallon of 100 F (38 C) water, as the eggs pass through special egg-cleaning machines. It both cleans and sanitizes the shells.

Cooking Tips

When applying an egg wash to bread in a bread pan, use a light hand. If you put too much on, it will dribble down between the dough and the bread pan, causing the loaf of bread to get stuck inside the pan when baked. (The same applies to pies: don't let any dribble down between the bottom crust and the pie pan.)

To apply egg wash to a loaf of bread being made and baked in a bread machine, wait for the final rise cycle (you have to get to know your machine first.) You can then either brush it on right in the pan inside the bread machine, or if you want to make sure that none will drip and burn, or if you're applying messy things like seeds after the egg wash, then just after the bread machine has finished its final punchdown and is about to move into the final rise cycle, take the dough out of the bread pan (leave the machine on), do your work quickly, and then set the dough back in the bread pan inside the machine, egg-washed side up of course.

You almost always have some leftover egg wash: discard if you were using it to brush raw meat or dipping raw meat or fish into it. If not contaminated in any such way, then you can pop it covered into the fridge and incorporate the leftover into scrambled eggs or another recipe in the next day or two.

Substitutes

You can use a commercial egg substitute instead of the wash, such as Egg Beaters™ or Egg Creations™. If the substitute is a liquid one, just use it straight, don't add any water.


Also try 1 teaspoon custard powder mixed with 1 tablespoon of water.

In older days when eggs were dearer, some frugal cooks would just use plain milk as a wash.

Vegan substitutes include soy powder mixed with water, soy milk, or an oil such as olive oil.
