Boil 12 eggs by placing them in a large pan with cold water. When the water is boiling, reduce heat so it’s just a simmer, cover with a lid and let the eggs boil for 10 minutes (you need the white to be firm so boiling for less time will make a lovely boiled egg but not as firm as it needs to be for this recipe). When the time is up, remove the eggs and place them in cold water to stop the cooking process.
