DIY Organic Food Colouring

I was chatting with a friend recently about how his kids are allergic to red food dye. It made me do some research, where I found that it contains plenty of chemicals, including petroleum. I decided to make my own food colouring from organic fruits and vegetables, and it was a total success! Here is how you can do it yourself at home. This is a great project to do with kids, too.

I used red cabbage to make a purple tone that turns blue with the addition of sodium bicarbonate. You can double the batch and only turn one half blue, keeping the other half purple, if desired. I added the blueberry step to show you how it makes another kind of purple tone. :)

Total Time: 1 hour

Yield: 5 colours

Supplies:

half a head of red cabbage, sliced into thin strips
water to cover cabbage
1/4 tsp natural sodium bicarbonate
half a cup of frozen organic spinach, thawed
1/4 cup water
1/3 cup blueberries
3 Tbsp water
1/4 cup cooked beets
3 Tbsp water
1/2 tsp ground turmeric
1/4 cup water

Steps:

To make the blue food colouring, place red cabbage in a pot and cover with water. Bring to a boil, then simmer for 15 minutes.

Return the purple water to the pot and simmer another 10 to 15 minutes.

Sprinkle in the baking soda, stir, and watch it turn blue.

To make green, puree the spinach and 1/4 cup of water together in blender until totally smooth. You can add a bit more water if it gets stuck.

To make yellow, in a small pot, boil water and turmeric for a few minutes. Stir well. Allow to cool.

Store colours in airtight containers in the fridge. They keep well for a couple weeks.

I use about a teaspoon of each for my batters and frostings. If you'd like a heavier tint, lessen any liquid in your recipe a bit, if possible, and add more colouring.
