Trying to flavor a hardboiled egg with cola can be a little more difficult than it sounds. You can't simply boil it in cola. (I know, I've tried. Twice.) So here are some simple instructions on how to marinate a hardboiled egg in cola.
eggs (as many as you want to make)
The first step is to make the hardboiled eggs. Place eggs into a saucepan and fill with cold water just until the eggs are covered. Place the saucepan over high heat and bring to a boil. Once the water has started to boil, remove from heat and let sit for 10 minutes. Remove the eggs and run under cold water until cool. Remove shells.
Place eggs in a plastic baggy and fill with cola just until the eggs are covered. Diet cola can be used instead for the more health conscious. Tie off baggy and let sit for at least 6 to 12 hours depending on the desired strength of the carbonation and cola flavor. Bon apetit!
These eggs were marinated for 6 hours.
