I was in chat talking with Itachi, SnowQueenFan and others, about the ingredients of the Dark Curse, and I'd like to hear more thoughts about this :D Here is my headcanon list of ingredients, and why they are used.

The show's Canon + My Headcanon

 * A lock of hair from those with the darkest of souls, to destroy happy endings.
 * The heart of "the thing you love most" to pay the price of such powerful magic.
 * A drop of true love to make the product of true love the curse breaker.
 * Water from the Lethe River  (First Curse), Memory Potion (Second Curse) or Enchanted Dreamcatchers (Third Curse) to wipe everybody's memory. Another option could be Memory Rocks from Arendelle's trolls.
 * Magic Ink to create new personalities, lives and memories for the people of Storybrooke, as well as creating Storybrooke itself. As we've seen in 4B, magic ink can change people's appearance (like Cruella's hair), people's personalities (like making Snow White evil), people's memories (like making Robin Hood and Zelena have memories of falling in love together in the AU). Maybe magic ink was used to write the Dark Curse scroll?
 * Water from the Acheron, which traps people in the Worse Place if touched in the Underworld, to trap people in Storybrooke, preventing them from crossing the townline.
 * The Clock of Evermore  (used in Wonderland by the March Hare to create a time loop, an eternal tea party), to create the daily time loop in Storybrooke (hence the time freezing)

Other Possibilities

 * Anti-Transformation Powder to turn people like Archie or Gus back into human beings.
 * Some kind of Portal magic (Enchanted Wood ashes, magic bean, an enchantment of the Apprentice's wand, etc.), to transport everyone to the Land Without Magic.
 * Some kind of  Magic-neutralizing item/substance  (Squid Ink, Fairy Dust, Magic Sand (from Out of the Past), etc.), to neutralize everybody's magic. It is most likely that this isn't necessary, and that the being sent to the Land Without Magic is enough.

What am I missing? Is there any interesting theories out there about other possible ingredients?
