1 l. Ribena or similar
1/2 l. sugar-free pink grapefruit squash
1 whole bottle mixed spice
1/2 bottle best-quality vanilla essence
1 slice of bread
1 plastic dinosaur
(for best results, ensure Thomas is fully in charge)
Pour entire contents of the first 4 ingredients into a Dualit toaster
Add slice of bread - make sure it is pushed in as far as possible
Finally place plastic dinosaur into microwave oven, and microwave on full power for as long as possible.
(NB: Daddy arrived before any lasting damage was achieved... Added to which Tom doesn't yet know how to use the microwave. But at least, the kitchen smelt nice.)
Here are the empty bottles - just to prove it. Although: did you really need proof??!
