Looking at the recipe more closely...it seems that the rice is added uncooked, at least based on the instruction to "wash and drain" before adding.
Anyone ever tried anything like this? My gut feeling is that it would be a disaster. If you cook long enough for the rice to cook then the meat must be ruined. Right?
It would depend how you cook it. Many Greek/Cypriot recipes call for raw rice - for instance, dolmathes (stuffed vine leaves), but these are cooked covered in the oven. I suspect these sausages may have to be cooked the same (i've never had them before).
