Prepare the hard-boiled eggs by boiling them until fully cooked and allowing them to cool.
In separate cups or small bowls, combine 1 cup of boiling hot water with 1 tablespoon of white vinegar for each spice (turmeric, hibiscus tea, and beet powder).
Add 1 tablespoon of turmeric to one cup, 1 tablespoon of hibiscus powder to another cup, and 1 tablespoon of beet powder to the third cup.
Stir each spice mixture until well combined with the water and vinegar.
Submerge each hard-boiled egg into the spiced color one at a time, allowing them to absorb the color for about 1 minute.
Use a spoon or tongs to remove the eggs from the spice mixture and place them on a plate or drying rack to dry.
Once dry, display or hide your beautifully colored spice-dyed Easter eggs and enjoy!
Note: The turmeric will turn the eggs yellow, the hibiscus powder will turn them a lavender blue, and the beet powder will turn them light pink. Adjust the amount of spice used or the soaking time to achieve your desired color intensity. This is a great way to use these ingredients if they are getting old. They will still dye your eggs.
(Fun fact: Butterfly pea flower, paprika, and rose petals did not dye eggs successfully.)
