There are occasions when eggs are non-negotiable in a recipe—like egg drop soup or quiche—however when eggs play a minor function, then why not use a substitute? Egg wash is a main instance. Utilizing it provides colour and shine to completed baked items like dinner rolls and pies, however when eggs are promoting at a premium value, it’s laborious to justify utilizing an egg wash in any respect.
Discovering a superb egg wash different isn’t solely helpful for saving a buck, however it may be a useful back-up even when eggs are plentiful. There’s at all times the event the place you simply ran out, or you’ve of us coming over which can be on egg-free diets. After some searching on the web, butter, mayo, milk, heavy cream, maple syrup, and bitter cream appear to be the widespread substitutes.

I whipped up a batch of my favourite biscuits and painted them with completely different finishes so I may evaluate them after baking. You’ll be able to see within the image above that there are eight biscuits. Along with the six options I discussed, I did one with precise egg wash so we will observe what we’re striving for, and one with completely nothing on it as a management.
25 minutes later, the outcomes have been in and I used to be truly fairly stunned. Every topping produced a unique outcome; some extra apparent than others. When egg wash is used as a topping (versus a binder), its major operate is to impart colour, shine, and go away no hint of taste, so that is what I used to be on the lookout for.

Palms-down, the winner was bitter cream. Dare I say it carried out even higher than the precise egg wash. (I attempted to seize the blinding shine within the image beneath.) The colour of the baked bitter cream coated biscuit was a phenomenal darkish brown, and the shine surpassed even the egg wash commonplace.

Runners-up have been mayonnaise and complete milk for his or her middle-of-the-road efficiency in each classes. For a vegan choice, maple syrup imparted beautiful brown coloring, however it had a decidedly un-shiny end and it leaves behind a refined candy taste (which may be good or unhealthy relying in your preferences).
Butter turned out the worst efficiency. I’d be unhappy, however I’ve been fooled by butter earlier than so I used to be anticipating the frustration. On each counts, the end paled compared to its rivals. Butter apart, no less than you’ve some choices for the following time you make a batch of biscuits, rolls, pastries, or pies. Save the eggs for after they matter most.
