With a clever bit of kitchen chemistry you can easily make your own green eggs, without any food colouring! The secret lies in a special pigment found in ordinary red cabbage, when cabbage juice is introduced to the alkaline egg whites the change in the pH causes the purple juice to turn a greenish-blue colour, it's completely harmless and produces a neat effect.
So for all you Dr.Seuss fans out there, get ready to have your favourite childhood story for breakfast.
Enough talk, let's make some green eggs (and ham), Sam I am!
Step 2: Chop, nuke and squeeze that cabbage
Then, transfer cabbage into a microwave-safe bowl with lid and microwave on high for about 4-5 minutes. This will soften your cabbage and release the juices. After microwaving your cabbage will be very hot, allow to cool at room temperature or in the fridge until you can safely handle the cabbage.
When your microwaved cabbage has cooled, place the soft cabbage into a doubled sheet of cheesecloth. Gather the edges of your cheesecloth and squeeze the cabbage over a mixing bowl, collecting the purple cabbage juice.
