Feta cheese is probably the most popular of all Greek cheeses and is made from goat's or sheep's milk (and in more recent times, cow's milk) and has a soft crumbly texture and a salty flavor.
Feta is made in many other countries (such as France, Romania, Israel ) and each style has its own unique characteristics. Feta is a very versatile cheese that can be tossed in warm pasta, added to appetizers, served in salads. Feta can be found in most grocery stores.
This is a very popular and easy to find cheese. Look for it in your grocery store or local cheese shop. Trader Joe's make a "light" feta which is excellent. Marin Cheese Company also makes very good feta cheese.
