What is a mixed spice with respect to a cake?
Mixed spice is a blend you find in the UK. It's a mix of cinnamon, ground coriander, nutmeg, ginger, and cloves. Some recipes call for mace, caraway, and/or allspice as well. It's a bit like garam masala, there's no set blend. It's as simple as mixing together equal quantities of each, although you may want to add double the mace if you opt for it.
