Fire Salt is an edible mix of many types of magical red powders and is held in a clear tube with a red, crystalline stopper.
The fire salt causes a burning sensation when consumed. Varying amounts of fire salts have varying effects. A small amount would cause an extremely intense spicy flavor, but if too much is eaten, it can cause the consumer to spew out fire form their mouth.
- In the Steven Universe comic issue #6, Amethyst used fire salt to win at a hot dog eating competition by "spiking" the other contestants' hot dogs with it, which of course, is cheating.
- The fire salt also appears in the RPG Attack the Light as a useable item. It makes all the attacks of the selected Gem burn enemies.
