Granny Bells, the Night Hag, has captured a PC (half-elf bard) and plans to eat her, as hags are wont to do. Granny Bells has a preference for sour and bitter food and an extensive array of monster parts and spices available for her cooking adventure. She's originally from Chult, but has since moved to Barovia, so she has access to ingredients from the Tomb of Annihilation campaign and the Curse of Strahd campaigns, as well as all items listed in the core rulebooks.
What should she throw into her cauldron along with the half-elf to get as sour and bitter a half-elf-soup as she can manage?
The ingredients must be:
- Actual cooking ingredients listed in one of the 5e rulebooks or the Curse of Strahd or Tomb of Annihilation adventure modules, described as especially bitter or sour
- Part of a monster from a 5e rulebook or the Curse of Strahd or Tomb of Annihilation adventure modules, described as especially bitter or sour. Granny Bells is not particularly concerned about the ethics of killing sentient monsters to prepare her food. (Obviously.)
All ingredients must also be edible for a hag. Assume the hag can eat essentially anything that is not made of rock/metal. Poisons and such do not bother her, but she's not going to eat a sword.
A required ingredient is a half-elf, obviously, but she's got that part covered. Granny Bells is not well versed in cooking and operates under the assumption that more ingredients is better, so the best answer will be the one that throws in the most bitter and sour ingredients. She'll get a bigger cauldron if need be.
