Dye Eggs With What's in Your Kitchen: Food Coloring 

For beautiful, natural, homemade colors you can dye eggs with food coloring, add foods you may already have to the cold water before cooking eggs. Experiment with onion skins, cut-up beets, spinach, tomato paste, coffee, tea, spices like turmeric or sugar-free gelatin. Wrap string around eggs to create fun patterns. To keep mess to a minimum, spread a plastic tablecloth and let the creativity begin.

Egg Storage

• Store hard-cooked eggs in egg cartons in the refrigerator if you don’t color them immediately.
• Hard-cooked eggs in the shell will keep safely up to 1 week.

 Important Safety Tips

• Eggs should not be left out of the refrigerator for more than two hours without risking food poisoning. If you plan to display decorated eggs longer than two hours outside the refrigerator, do not eat them. Cook and refrigerate extra eggs for eating, and throw out hard-cooked eggs used for decoration.hard-cooked eggs in egg cartons in the refrigerator if you don’t color them immediately.
