Marbled Eggs Hardboiled eggs Food coloring Vinegar Cooking oil Containers for the dye mixture (mugs are fine) Paper towels Few spoons In each container combine one tablespoon of each of the following: oil, vinegar and your choice of food coloring. Add enough water to make the liquid deep enough to cover an egg. Swirl the liquid with a spoon, and quickly lower and raise an egg into it. Pat dry with a paper towel, and repeat with a second color. Swirl into a third color, if desired. Some white areas can be left on the egg. Gently pat dry the completed egg, leaving a bit of the oil to give the egg a varnished look.
