Ingredients

Scale

Eggs and Dye

  • 12 large eggs
  • 1 1/2 cups frozen blueberries, thawed
  • 1 1/2 cups hot water
  • 3 tablespoons distilled white vinegar

Filling

  • 12 large egg yolks (from the hard-boiled eggs)
  • 9 tablespoons mayonnaise
  • 2 tablespoons liquid chlorophyll
  • 1/4 teaspoon salt
  • 1/4 teaspoon black pepper
  • 3 tablespoons minced fresh dill
  • 2 tablespoons minced fresh chives
  • 1 large clove garlic, crushed

Garnish

  • 1/2 tablespoon poppy seeds

Instructions

  1. Make the Crackled Eggs: Place the eggs in a saucepan and cover them with cold water, ensuring the water is about 3 inches above the eggs. Bring to a rolling boil over high heat, then reduce to a gentle boil and cook for 9 minutes and 30 seconds.
  2. Ice Bath and Crack Shells: Transfer the eggs to an ice bath and let them cool for 10 minutes. Once cooled, gently tap the eggshells all over to create a fine network of cracks without removing the shells.
  3. Dye the Eggs: In a blender, combine the thawed blueberries, hot water, and distilled white vinegar and blend until smooth to prepare the natural blueberry dye.
  4. Marinate Eggs in Dye: Place the cracked eggs into a gallon-sized zip-top bag. Pour the blueberry mixture over the eggs, squeeze out excess air, seal the bag, and refrigerate for 24 hours. Rotate the bag occasionally to ensure even coloring.
  5. Dry the Dyed Eggs: After 24 hours, transfer the eggs to a wire rack and let them air dry in the refrigerator for 1 hour, allowing the color to set and the shells to dry.
  6. Prepare the Filling: Carefully peel the eggs to reveal the crackled, dyed surface. Slice each egg in half lengthwise and remove the yolks into a large bowl. Mash the yolks until smooth.
  7. Mix Filling Ingredients: Add mayonnaise, liquid chlorophyll, salt, and black pepper to the mashed yolks. Mix thoroughly to create a creamy and smooth green filling. Stir in the minced fresh dill, chives, and crushed garlic until fully combined.
  8. Assemble the Swamp Eggs: Spoon or pipe the green yolk mixture back into the hollowed egg white halves, filling them generously.
  9. Garnish and Serve: Sprinkle the filled eggs with poppy seeds for texture and contrast. Serve chilled as a festive Halloween appetizer.

Notes

  • Use fresh eggs for boiling and allowing proper peeling.
  • Handle eggs carefully to avoid breaking the cracked shells before dyeing.
  • Liquid chlorophyll enhances the green color naturally but can be omitted if unavailable; you may add a small amount of green food coloring as a substitute.
  • For a stronger blueberry flavor, use fresh blueberries if possible.
  • Marinate eggs longer for deeper color; up to 48 hours can intensify the effect but may darken the shell.
  • Chilling eggs after cooking improves peeling ease.
  • Make sure to remove air from the bag during dyeing for consistent coloring.
