Halloumi is traditionally made from a mixture of sheep and goat milk.
The Cypriots have attempted to try to obtain PDO certification for this cheese. However, I believe, this has been unsuccessful. There will be enough bickering with the larger companies trying to include cows milk in the PDO. Objections have been sent from Dairy Australia, British cheesemakers, US, Turkey and Kuwait. This might drag on.
So we will stick with name Halloumi for now.
