Instructions

1. Place 12 large eggs in a large saucepan and add enough cool water to cover the eggs by at least an inch. Bring to a boil over high heat. Remove the pan from the heat. Cover and let eggs sit for 12 minutes. Meanwhile, prepare the decorations and an ice water bath.
2. Chop 2 chives into 1/2-inch pieces to create a stem for the pumpkin eggs. Make an ice water bath by filling a large bowl with ice and water.
3. Using a slotted spoon, transfer the eggs to a work surface. Gently tap each egg on the counter to crack the shell in a few places. Place in the ice water bath for at least 1 minute. Peel the eggs. Cut each egg in half lengthwise.
4. Carefully squeeze the egg yolks into a medium bowl. use your fingers to wipe out any residual yolk in the whites. Arrange the whites cut-side up in a single layer on a serving platter.
5. Mash the yolks with a fork until completely crumbled. Add 1/3 cup mayonnaise, 2 teaspoons Dijon mustard, 1/2 teaspoon kosher salt, and 1/2 teaspoon black pepper. Mash into a smooth paste. Taste and season with more kosher salt as needed.
6. For yellow mummies, transfer 1/4 cup of the yolk mixture to a small ziptop or piping bag. Cut a 1/2-inch off one bottom corner of the ziptop bag or 1/2-inch from the bottom point of the piping bag. Pipe the filling into 6 of the egg white shells. Smooth the filling by gently pressing on it with your fingers. Top each mound of filling with 2 capers to make eyeballs. Scoop 3 more tablespoons of the yolk mixture into a separate bag and snip a 1/4-inch opening. Pipe zigzag lines across the eggs to "wrap" the mummy.
7. For purple one-eyed monsters, scoop 1/4 cup of the yolk mixture into a small bowl. Add a drop of purple food coloring and mix until fully combined, adding more coloring as needed until purple. Spoon the filling into 6 of the egg white shells. Smooth the filling by gently pressing on it with your fingers. Top each mound of filling with 1 olive slice for an eyeball.
8. For orange pumpkins, scoop 1/4 cup of the yolk mixture into a small bowl. Add a drop of orange food coloring and mix until fully combined, adding more coloring as needed until orange. Spoon the filling into 6 of the egg white shells. Smooth the filling by gently pressing on it with your fingers. Run the tines of a fork down the filling from top to bottom to create pumpkin ridges. Place a chopped chive at the top of the filling to make a stem.
9. For green spider’s nest, scoop 1/4 cup of the yolk mixture into a small bowl. Add a drop of green food coloring and mix until fully combined, adding more coloring as needed until green. Spoon the filling into 6 of the egg white shells. Smooth the filling by gently pressing on it with your fingers. Top the filling with 1/4 teaspoon poppy or black sesame seeds.
