Bring a pot of water to a boil. Add the eggs to the pot. Boil for 11 minutes.

Remove from heat and rinse with cool water for a minute.

While the eggs are still very warm, peel them.

Place the peeled eggs in the 'v' shaped cardboard. Place a chop stick over the top and secure with a rubber-band.

Allow to cool in the fridge for 3 hours or overnight.

Remove the eggs from the cardboard and slice into hearts!
