Tie-dye rainbow biscuits

Tie-dye rainbow biscuits

Edd Kimber's marbled biscuits are a fun weekend baking project. You can choose how many colours to use in the icing and how to swirl them together, but Edd's preference is for the full rainbow, with a little white to make them pop. The technique takes a bit of practice but the results are worth it. The biscuits are delicious, however they’re decorated!
