What is Halloumi cheese? Can I substitute other cheeses?
Traditionally prepared from sheep's milk in the Greek island of Cyprus, Halloumi is a soft curd-like cheese free of rennet and safe for vegetarians who do not eat rennet. (See also: Is cheese vegetarian?) Many similar cheeses are prepared by dairy and goat farmers in Canada and the United States. For legal proprietary reasons, these cheeses are usually called "Halloumi-style" or "grillable" cheeses.
Depending on your recipe, Halloumi is not usually easy to substitute. Tofu or Indian paneer may be used in some recipes, but it won't be quite the same as halloumi or a similar "grillable" cheese.
If you can't find halloumi cheese locally where you live you may want to try shopping online for Halloumi.
