Her idea is simple, really. Hard boil some eggs with blueberries (known for their natural staining ability) to prep them for their web creations. The eggs will turn a light shade of gray.
Remove the eggs and whack them gently with the handle of a whisk- to create a nice 'crack.' Place the cracked eggs into a bowl and pour the blueberry cooking liquid over the top. Place the bowl in the fridge to give the tinted liquid a chance to do its magic, and let the eggs cool completely.
