GREEK FRAPPE!

We've had really hot days here in the North-West corner of Italy these days! It feels like full summer... It's kind of a mini heat wave, with temperatures that have climbed up to 30-32° C and plenty of sun and blue skies.
It feels like summer, so I've been thinking about my favorite summer drink in Greece: Greek frappé! I'm going to taste it very soon, as I'm off to my beloved island of Rhodes this Tuesday for a week!
Greek frappé or Café frappé (Greek: φραπές, frapés) is a foam-covered iced coffee drink made from instant coffee. It is very popular in Greece and Cyprus, especially during the summer.

This drink is so popular in Greece that there is even a website devoted to it, Frappe Nation! Here is the description from the site:

"A frappé is nothing more complicated than instant coffee, sugar, and a small quantity of cold water shaken vigorously together to produce a thick foam, then poured over ice in a tall glass, and finally topped off with milk or water. That basic formula gets muddled not only by personal habits but also by the homespun guidelines passed on by its practitioners.”
"It may be best to describe the frappé formula in terms of volume proportions. A gliko (“sweet”) frappé, for example, is typically made with between 1 1/2 and 2 measures of sugar per 1 measure of coffee. To prepare a metrio (“medium sweet”), up to 1 measure of sugar should be mixed with 1 measure of coffee. To create a thick, creamy foam, the ideal coffee-to-water ratio is about 1 part instant coffee per 4-5 parts water."

The basic recipe:
"1. Place 2 teaspoons of instant coffee, sugar to taste, and a splash (3-to-4 tablespoons) of cold water in a shaker, jar, or drink mixer. Cover and shake well for 30 seconds or, if using a standing or hand-held drink mixer, process for 10 seconds to produce a thick foam.
2. Place a few ice cubes in a tall glass. Slowly pour the coffee foam into the glass. Add a splash of milk (evaporated or regular), if desired. Fill with water until the foam reaches the top of the glass. Serve with a flexible straw."
