Place room temperature eggs in a single layer in a pot filled with cool water.
Bring the water to a gentle boil, reduce heat to medium low and cook for 15 minutes. Test the eggs doneness by spinning the egg on the counter, if it spins without wobbling the egg is cooked.
Once eggs have cooked, allow them to cool.
Dissolve the dye in a class of hot water.
In a pot containing hot water, add one cup of vinegar and the dissolved dye, stirring well.
Carefully add the cold eggs and allow them to dye for 3-5 minutes. To check the color of the eggs, use a spoon to lift an egg out of the dye to see the color.
Place egg back in dye if it needs more time.
Using a slotted spoon remove eggs from water and dry them with a paper towel.
To make eggs shine, take a clean paper towel and moisten it with olive oil and rub the egg carefully.
Place dyed eggs back in their original container, which is perfect for storing the eggs. Return the eggs to the refrigerator until ready to use. Kalo Pascha!
Notes
You may want to wear disposable gloves, as the dye will stain your hands.
