What you need :
A cauldron, (can be purchased or cast if you have the skill and material)
Something to stir with (can be a stick or anything else... corpse's dismembered arm perhaps?)
Children broth (may take at least four toddlers to get the right thickness)
Three Nag's toes (must be particularly naggy nags)
A dash of dead man's dandruff
Last but not least, and definitely the hardest to acquire. Sixteen zombie eyeballs.
Add children's broth immediately in cold water and bring to a boil. Once at a boil, add other ingredients and boil for ten minutes.
Serve with a skull.
