People are using common kitchen ingredients to dye Easter eggs instead of synthetic food dyes. Vegetables, berries and spices can make yellow, red, green and blue shades. Natural dyeing is fine for eggs you will eat, because dye does not make the eggs unsafe by itself.
Food safety matters. Hard boiling removes the egg’s outer coating and can let bacteria enter through the shell pores. To reduce risk, eat hard‑boiled eggs within one week and keep them refrigerated. Do not eat eggs that were left unrefrigerated for more than two hours, or for one hour in very hot weather.
To color eggs, boil the chosen ingredients in water, strain the liquid, add a little vinegar, and leave the eggs in the dye until the color is right.
