A jar of small, faintly luminescent mushrooms pickled in vinegar and herbs, harvested from damp caves. One jar (4 servings) costs 3 gp and adds an eerie glow to meals.
Recipe
Gather 1 pound of fresh glowcap mushrooms and rinse thoroughly.
Simmer in a pot with 1 cup of vinegar, 1 teaspoon of dill, and a pinch of garlic for 15 minutes.
Transfer to a jar, seal tightly, and let sit for at least 3 days before eating.
