I love to use gel food coloring to dye eggs. Here's how to do it: Mix 2-3 drops of gel food coloring and 2 tablespoons of vinegar in 1 cup of warm water. Add more gel food coloring as needed to get water to desired color. Stir until thoroughly combined. Place eggs in the mixture and let sit until the desired color is reached. Place on a drying rack to let the color set. Once eggs are dry, wipe them with a little canola oil to make eggs shiny and bright.
