Dying Easter Eggs With Food Coloring And Vinegar. Don't be afraid to experiment with the amount of drops to get the color you're looking for. Your good old food coloring from the grocery is an acid-base dye and the vinegar traditionally used to dye eggs helps the food coloring to bond to the eggshell.
Now unwrap and check out all the cool colors. You know the drill: Add color tablets to jars of vinegar, dip your hard-boiled eggs, and let them dry on a flimsy cardboard tray. So for purple only, we placed the egg directly into a bowl of vinegar.
When the water starts to boil, set a timer for two minutes.
Pour a tablespoon of vinegar over the egg and watch it fizz up.
Put a single layer of eggs in a saucepan and cover with one to two inches of cold water. Another option is to boil eggs in water and edible dye components, such as red cabbage, spinach, and red wine. Gently bring eggs to a boil.
