FANTASTIC FOOD TRICKS
Do you want to make colorful omelet?
There's an option is to use butterfly pea flowers. Steeping the flowers in boiling water produces a deep, vivid blue that is safe to add to any food or drink. While red cabbage juice has a distinctive (some would say "unpleasant") flavor, butterfly pea does not have a flavor. You can get a red cabbage at pretty much any grocery store, but you'll probably have to go online to find butterfly pea flowers or tea. It is inexpensive and it lasts practically forever.
To make blue eggs, simply prepare butterfly pea tea in advance. Mix in a few drops of the tea with the egg white to achieve the desired color. Cook the egg. You can drink or freeze any leftover tea.
Butterfly pea flower, like red cabbage juice, contains anthocyanins. The color change is different though. Butterfly pea is blue under neutral to alkaline conditions. It turns purple in very dilute acid and hot pink when more acid is added.
