But in order to shape these yummy delicacies you need cute snowflake, gingerbead men and star shaped cookie cutters. The best cookie cutters are made with aluminium and to find  aluminium for the cutters you need an ore like Bauxite.

Bauxite is not actually a mineral, but, similar to Monazite, the term describes a group of minerals that represent the primary ore of aluminium. These minerals include Gibbsite, Bohmite and Diaspore and although it is not a particularly attractive mineral is extremely valuable commercially. Unfortunately it isn’t found in the UK (as far as I know – please correct me if I’m wrong!), but you can find it in nearby France!
