Besides cookies and graham crackers, what biscuit can form a cheesecake base?

Besides cookies and graham crackers, digestive biscuits can form a cheesecake base.

Digestive biscuits are especially common in British and other European-style cheesecake recipes. They are usually crushed into fine crumbs and mixed with melted butter, which binds the mixture when it is pressed into a tin and chilled or baked.

This base is similar in purpose to a graham-cracker crust, but the ingredients reflect different food traditions. Graham crackers are strongly associated with North American cheesecakes, while digestive biscuits are a familiar supermarket biscuit in the United Kingdom and many other countries.

Cheesecake bases are not limited to one formula. Depending on the recipe, cooks may use crushed cookies, pastry, or sponge cake. The filling may also be baked or left unbaked, so the biscuit base is one of several regional and stylistic choices rather than a universal requirement.
