For the past thirty years, this has been the preferred coffee preparation method in Greece. This recipe is a great way to make a naturally foamy frappe.
In a shaker or blender, mix together coffee and sugar to taste. Shake contents for about 30 seconds or blend for about 10 seconds. The result should be simply foam.
Pour into tall glass and add ice cubes. Add remaining water and milk to taste. Insert straw.
Milk and sugar are optional and according to taste.
