Certainly. But it's much easier to measure out the right amount in liquid form.
I bought a dripper bottle from a health store. 20g salt, 80g water. Very easy, very cheap.

I found it improved drastically after adding a few drops of saline solution.

What a horrible experience. The egg mixture coagulated, making the "frothy head" taste like spiced wet scambled eggs, followed by hot watered down cognac.
I must have done something horribly wrong. Otherwise people wouldn't have enjoyed this cocktail since before 1862.

How much beer are you adding? I don't think I'm hitting the right proportions here.
