Purple food colouring is a great colour to have on hand in the spring. The colour looks bright and cheery on Easter eggs, in frosting or as a decorative touch in mashed potatoes or cream sauces. Creating purple food colouring cane be done in seconds.

Place ten drops of red food colouring into a small bowl.

Add five drops of blue colouring to the red.

Whisk the red and blue together to create purple.

Drop in additional red food colouring, one drop at a time, to lighten the purple or more blue colourant to darken it.

Use the purple food colouring as directed on the recipe you are creating.
