Dear Lord, I am slightly gagging at the mere description of that sauce.
The donair, a uniquely Canadian take on the Greek gyro or the Turkish doner kebab, is the creation of King of Donair’s founder, Peter Gamoulakos. A Greek immigrant, he had a hard time selling gyros at his pizza restaurant before he made some changes to suit the Canadian palate. Mr. Gamoulakos traded the lamb for thinly sliced beef and the thicker Greek-style pita for a slimmer one. Instead of tzatziki, the notoriously messy sandwich is topped with Mr. Gamoulakos’s signature donair sauce, made from condensed milk, vinegar and garlic.
