Like magic! The water from cooking red cabbage will dye boiled eggs a beautiful blue/aqua colour. The depth of colour will depend on how long you leave the eggs in the water. As a general guide, 30 minutes will yield a very pale blue, and soaking overnight will give a deep blue colour. 

You will need:
1/4 to half a red cabbage, roughly chopped
2 tablespoons white vinegar
2 tablespoons salt
  1. Place red cabbage into a large saucepan, cover with plenty of water, and bring to the boil.
  2. Reduce heat to a low simmer and allow to cook for 30 minutes.
  3. Strain, remove the cabbage. 
  4. Stir 2 tablespoons white vinegar and 2 tablespoons salt into the hot cabbage water, set aside to cool to room temperature.
  5. For best results pour into tall jars.
  6. Hard-boil the eggs you wish to dye. ( Our 'Duck' eggs are perfect as they are white) 
  7. Allow eggs to cool to room temperature.
  8. If you want a marbled effect, take 2 plastic sandwich bags, place over your hands like rubber gloves, then rub the bags over a block of butter. Scrunch the bags into the butter to get an uneven coating of butter on the bags.
  9. Now take 1 egg at a time (with the bags still on your hands) and pass the egg from hand to hand, randomly touching the egg gently with the buttery bags.
  10. Gently place the egg into the cabbage water jars and repeat with other eggs.
  11. For plain colored eggs, simply place into the cabbage water without butter.
  12. Using a slotted spoon, remove eggs when the desired intensity of colour is reached.
  13. Place eggs onto wire racks to dry.
  14. Use eggs as decorations at your Easter celebration table.
