Input: CONTEXT: The proteins in a fresh egg are too viscous, even when thoroughly beaten, to wash a baked good.The water thins the proteins so you get a nice glaze instead of a layer of scrambled egg.Older eggs have sometimes degraded enough that they don't need the water but it is easier to always add water than to make a subjective judgement on the state of your egg proteins.  <sep>  Q: What's the purpose of adding water to an egg wash? A: The water thins the proteins so you get a nice glaze instead of a layer of scrambled egg  <sep> FOLLOWUP_Q: Many recipes I've seen call for beating a tablespoon###or so of water in with the egg for an egg wash.###What is the effect of adding the water to the egg wash when baking?

The water thins the proteins so you get a nice glaze instead of a layer of scrambled egg
