Parsley Soda: The Preferred Beverage of the Fashionable Elite

Step 1: Parsley Water

Wash and finely chop the parsley. Place in pot and add enough water to cover. Bring to the boil and let simmer until water absorbs parsley flavor to taste. 
Meanwhile, juice the 2 limes. You can boil lime zest along with the parsley if you would like.

Step 2: Strain and cool

Strain the parsley water into a bowl. Add chopped ice until the water is warm. If it is too hot it will kill the yeast. Add the lime juice.

Step 3: Filter

You can filter out the lime pulp and small pieces of parsley with a coffee filter. It may take quite some time for it all to pass through, so you may prefer just to pour it through a fine strainer a few times.

Step 4: Mix, bottle, and shake

Using a funnel, pour your concoction into a plastic 2-liter soda bottle. Add 1 to 2 cups of sugar, and the yeast. Add water until bottle is almost full--leave an inch or two of air at the top. Cap the bottle and shake to dissolve the sugar. 
Leave bottle to sit for a day or two until pressure has built up to the point that the bottle does not indent when you squeeze it. Put it in the refrigerator to stop the fermentation. If you let it sit too long, the bottle will explode.

Step 5: Enjoy, become the envy of your friends and enemies

The parsley adds a subtle crispness to the soda. 
Serve with appropriate panache.
