When you select a cocktail, you are brought to the cocktail details page which shows the ingredients needed for the cocktail, a beautiful image of the cocktail and its components, and of course, the cocktail preparation. In addition, the details screen also shows cocktails which are similar to the one you are looking at. Right-clicking (or swiping up from the bottom edge) brings up the application bar, which in a cocktail detail screen allows you to add the cocktail as a favorite and/or pin it to the Start Screen.

Cocktail Flow was one of the apps I used to show off Metro design when my Windows Phone was new, and I am sure it will be a Windows Store highlight too. Team Distinction have a track record of extremely well-designed apps which also perform very well and Cocktail Flow for Windows 8 is yet another example.
If you are running Windows 8 Release Preview, go ahead and get the app from here.
