I guess most of us love eye appealing food despite whether you are an Adult or kid. As a mum of one, I hardly used food gel/colouring in our food but in order to achieve the eye catching colours for this Rainbow Pancake I have to use tiny bits of it for the effect. And to obtain the vibrant colours, you could mix your food colouring with some water before adding to your favourite pancake mix, in this way it could prevent over mixed of the pancake mixture and leaving you with nice and fluffy pancakes.
