Each verse in the poem provides a clue to the dish. You will be spoilt for choice on what to cook but only use a total of three ingredients.
Charlie needs the ingredients vanilla, curry and cinammon. Which numbers do these spices lead you to? Can you find the numbers in the table on the front page?
If you follow the paths of the three correct ingredients then you will get the numbers 1, 4 and 5. Therefore you are looking for an elk on the next envelope.
