Spas (soup)
Spas is a yoghurt-based soup. It is a traditional dish in Armenia. It can be served hot or cold. Besides yoghurt, the main ingredient is hulled wheat, or rice.
An egg or egg yolk is included, to prevent the yoghurt from curdling.
Sometimes a green leaf vegetable such as spinach is added, or herbs are used as a garnish, and when hot it can be served with meatballs included.
