Feta cheese is a white, slightly aged cheese usually made of lamb milk. It can be crumbly or creamy. It tastes similar to cheddar cheese in terms of tanginess. It is more powerful than sharp cheddar cheese. Blue cheese is the most powerful tasting and smelling cheese that I have ever had. It tastes good but needs some getting used to. Blue cheese is rotten (on purpose) with mold, which is what gives it the sharp flavor). I think it is a french Brie cheese before it became rotten. Blue cheese is good on salads, but only a few teaspoons. Feta cheese is good on salads and can be used less sparingly than blue cheese (four to five teaspoons).
