my very own rainbow


No fancy, wordy-smithy introductions necessary for this post – just an exuberant and ever so excited exclamation: “I JUST MADE WATERCOLOURS!!!!!”

Edible. Natural. Easy. Beautiful.

I found the recipe in an ‘eco’ magazine a friend of mine had, and was immediately determined to have a go.


What you need:

1/2 cup bicarb soda

1/4 cup corn flour

1/4 cup white vinegar

1 tsp sugar syrup

natural food colourings (make your own with cold-pressed vegetable juices [think carrot, spinach] & spices [turmeric, paprika] or you can buy some here)*

ice cube or paint trays


What to do:


1. Mix the dry ingredients together

2. Add sugar syrup and vinegar and stir immediately with a fork
(the mixture will froth but mine didn’t overflow, and quickly settled down as I stirred it)

3. Mix small amounts of the mixture with natural food colouring for the colours you want.
(The more colouring you use the darker/stronger the paint will be, obviously!)*
(And no matter how much it looks like icing, resist the urge to lick your fingers…it’s not icing, it’s bicarb slurry. And it tastes revolting!!)

4. Pour into your trays and use them straight away or let them set and use them just like any watercolour you’ve ever used before.
(It took a few days for all the liquid to evaporate, so set them aside in a safe place. In summer they’ll probably set/dry a lot more quickly).

5. PAINT PAINT PAINT PAINT PAINT!!! And glory in the sheer joy of making something so wonderful from scratch!


* Unfortunately I found that the natural red colouring from the bottle reacted with the bicarb and turned grey. I also tried using raspberries but had the same result. (Useful tip for how to get grey paint though). In the end I used ordinary non-natural red food colouring for the red and purple. Some more experimenting is obviously needed…
