I am thinking of using an iframe device for displaying the ingredients and another iframe device for the picture if the cocktail.
The ingredients iframe could load a logfile where the ingredients are copied to and the picture iframe does the same with the pictures of the cocktails. Have a look at the rules for an example of the paths and how you could set it up.
So you could use a rule like
IF button tequila-sunrise is pressed then execute "mv /home/pi/cocktails/pictures/tequillasunrise.jpg /home/pi/cocktails/tmp/cocktail.jpg" and execute "mv /home/pi/cocktails/pictures/tequillasunrise.txt /home/pi/cocktails/tmp/recipe.txt"
