It can be tricky to create an even crust made from a biscuit crumb mixture for a cheesecake or slice. An easy way to ensure you get the most even crust is to first sprinkle the crumb mixture as evenly as possible over the entire base of the pan and then use the flat base of a glass to press firmly, and evenly, down to compress it. To finish slide the glass across the base in a circular motion to even the surface.
