A bread wash is applied before baking to create a shiny, matte, light, and golden brown appearance to the bread and pastries. The most common and popular bread wash is egg wash.
But bakers would also use butter wash, especially if they run out of eggs. Will there be a difference between the two bread washes?
Here’s a quick egg wash vs butter comparison to help you choose which bread wash you should use.
Comparing Egg Wash & Butter
Egg wash is more accessible and affordable than butter wash, providing a better appearance to baked products. It also helps to glue and let the decorations stick to the surface of bread and pastries.
“Butter or cream create softness and shine, but these don’t brown quite as well as milk or eggs.”– Kimberly Blough, Writer
Using beaten eggs gives color to bread while using butter will result in bread with a softer texture and richer flavor .
Key Differences You Should Know
An egg wash combines egg and liquid, like milk, cream, or water. It is usually applied to the surface of yeasted bread, pastry shell, or pie crust to create a golden brown color.
Meanwhile, a butter wash was sometimes used as a substitute for egg wash. Some recipes also call for butter, resulting in a different color and texture than egg wash.
Egg wash has many variations leading to different results. Add less liquid for the darker and shinier crust and maintain a 3:1 egg-to-liquid ratio.
An egg wash that uses water produces a crisper crust with a deep brown appearance, while milk or heavy cream creates a softer crust.
On the other hand, melt butter at a low flame and whisk in the milk to create a butter wash. Ensure that you do not burn or brown the butter.
Using egg wash in your baking process is cheaper than butter. You usually only need an egg and water, but some bakers use milk or heavy cream to replace water.
You would only need a small amount of milk or cream, so it would not cost too much. Besides, eggs are a common ingredient in most kitchens.
An egg wash would impart a very golden and shiny appearance to bread and pastries, more than the butter wash. Include the egg yolk for a better appearance of pies and pastries.
But if you’re looking for a shiny and clear finish, leave it out and use only egg white.
A butter would only produce a lighter brown color or more rustic-looking baked products.
An egg wash adds some crispiness to the baked goods, while butter softens some pastries as it melts inside the oven due to heat. Egg wash would also make the bread’s surface to be glossy.
In addition, it helps decorations, spices, sugars, or seeds, to stick better to the surface of the baked goods than butter. When using butter, the decorations tend to slip off the surface of your bread and pastries.
Butter would enhance the flavor of your baked goods, incorporating an undeniable richness to the end product. In comparison, egg wash helps lock in moisture and seal fillings for bread and pastries.
Use both washes sparingly to avoid a greasy baked good. Moreover, butter could also be used as a finishing as it will lend a richer flavor to the dish.
But what makes your cake eggy?
Including butter wash in your baking process results in a greasy baked good. It burns quickly and melts when exposed to high heat, softening some pastries that are supposed to be crispy.
It is also unsuitable for those with dairy or milk protein allergies because it is made of dairy products.
Using too much egg wash on your baked goods can ruin them. The egg wash will dribble down unwanted areas, causing the bread or pie to get stuck inside the pan. It can also prevent the pastry from puffing.
It can make the baked products heavy and dense and seal the slits on the top of your bread or pie.

Sum It Up
Egg wash has more advantages to your baked products than butter wash. The egg is a common ingredient in our kitchens, and by mixing water, you can already have an egg wash that results in appetizing bread and pastries.
