Want to know how to make Unicorn Noodles that change colour from Purple to Pink?
It’s super simple – Just cut up some purple cabbage, place in a pot of boiling water and wait a few minutes until the colour of the water changes. Now add your noodles and boil till soft.
Finally, squeeze lemon juice over the noodles and watch the magic happen!
But How? Basically, cabbage juice acts as an indicator, meaning it changes colour as it’s pH changes. A pigment in red cabbage called anthocyanin changes colour when it is mixed with an acid like lemon juice. Simple as that!
Will have a recipe using these colour changes noodles up soon!
