Goop (3.5e Equipment)
From D&D Wiki
Goop: This magical goop, when eaten, causes the consumer to gain 2 lb. in weight for every 1 lb. of goop that he consumed. This is a 20 pound jar. However, if this goop is tasted, it is so delicious that the eater must make a Will Save DC 12 or continue to eat until the jar is empty. Goop adds a +4 circumstance bonus on Craft (cooking) skill checks. Goop is a light gray color and mixes well with most foods. A jar of goop costs 40 gold pieces. Upon inspection, with detect magic, it glows with a faint aura of transmutation magic.
