This isn't your normal Collins, oh no. This has a little extra ingredient which Monica says is sure to catapult you to new heights of cocktail creationist. A little thing called Earl Grey soda.
You can make this yourself but you will need a soda siphon. All you need to do is put strong, brewed Earl Grey tea though the siphon and there you have it. Simple.
Just one more thing before you can start, if you want to make your own sugar syrup, just mix two parts sugar to one part hot water and stir until dissolved.
Now that's all out of the way, lets get on with it. The ultimate Grand Marnier Collins recipe is right here...
