While holding the pouch, you can take a Magic action to expend 1 of its 10 charges, name any nonmagical food seasoning (such as salt, pepper, dried plum bark, or stardust cumin), and retrieve a pinch of the desired flavoring — enough to season a single meal.
The pouch refills its stock through unknown means, drawing trace essences from the surrounding Weave. It regains 1d6 + 4 expended charges daily at dawn.
Those trained in Arcana or with a nose for the exotic say it sometimes produces spices no longer grown on any known world.
