Cheesecake is a large family of sweet, cheese-based custard cakes. Cheesecakes are generally made with soft, fresh cheeses. Other ingredients such as sugar, eggs, flour, and cream are often mixed in as well. Typically, the filling covers a crust, which may be pastry, cookie, or digestive biscuit.
The word cheesecake is also used to describe the creamy, cheesy flavour of the dessert. There are also savoury cheesecakes, often flavoured with blue cheese and served as hors d'oeuvres or with accompanying salads.
