Is it possible to substitute the saline solution with normal salt?

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.

I've been through 4 bottles of montenegro since I discovered this cocktail just before christmas.
It's a crowd pleaser and a great cocktail for friends who are driving but want something special.
Every friday at sunset, it's monte mule time!
I use lemon instead of lime and if I want it more boozy, I use 2 shots montenegro.

I know exactly what you mean. Each time I buy a bottle, I promise myself I will try some of the other great cocktails with it.
15 Monte Mules later, oh well, maybe next time...

I have an easier method:
Put the water and gum arabic powder in a tall container and use an immersion blender to mix it.
Add half the sugar, and blend again to dissolve some of it.
Add the rest of the sugar, and blend for about a minute.
Pour the mix into a bottle, and shake it until the sugar is dissolved.
The syrup is now very aerated, but it will clear up completely overnight.
No heat is required.

Pretty good. Any reason this is shaken and not stirred?

Challenge accepted!
Oh, wait. This is very tasty. You win. Again...

Using a homemade sharpened spoon, it took less than four minutes to hollow out the pineapple. That made it much less of a hassle.
I also added some passion fruit syrup, and it didn't make it any less delicious...
