The cakes were both made by the same method. A packet mix with food colouring, yellow or green, then cut and sculpted, coated with coloured buttercream, followed by coloured fondant, and features in more fondant. The Thunderbird two was a double cake batch baked in a lasagne dish, the Thunderbird Four cake, was a single mix in a loaf pan to get the height.
To set them off I made a Tracy Island using a round table, a blue tablecloth, a washing basket, and a green duvet. The final touches were the rocket toys we had to represent Thunderbirds 1 and 3.
