I just used red and yellow food coloring to achieve the orange color, and paprika on top. I used a sharp knife to create a striated look for the pumpkin. I used a single lettuce leaf cut into really thin strips for the pumpkin stems. My boys loved this recipe!
For next time:
I wonder if a melon baller would have been better to get a more uniform look. I should have wiped the whites before I took the photo.
