Answer to Puzzle Contest (from the winner):

"Kelpie-A Scottish water spirit usually a horse that drowned its riders; any breed of sheep dog originating in Australia. Kelp is the manufacturing ingredient and pie is the baked food."

Technically the manufacturing ingredients are alginates, which are extracted from kelp. A kelpie is a type of sprite. The reference to a "soft drink" hinted at this (Sprite).
