Rainbow French fries cooking tutorial | FOOD HACK DIY

While I was laying in bed last night high as a kite on cold & flu tablets, this silly idea came into my mind..... 
'I need to try to figure out how to make rainbow hot chips!' 

So today for lunch I thought I would give it a go. I could not believe that it worked and that it was so cheap and easy. One of the best Rainbow food Hacks I have done

Below is a picture tutorial of how I created Rainbow French Fries and explained step by step. I wish I had some purple food colour to try. I didn't bother trying yellow as it wouldn't make much difference to the hot chips. 

I did not add enough green to the water so those chips came out pretty light but still worked a little.


1| Get your food colouring together and some frozen chips. You could use potatoes and cut them into chips but this was easier and I didn't have any potatoes on hand. What's the point of a kitchen food hack if you have to add more cooking prep work

2| Fill some cups with warm water. Add about 10 drops of food colouring and mix.

Drop your fries in each colour and let them sit for about 3 minutes. You could use bowls for larger quantities if you wanted, just add more food colouring. The more drops you use the darker the colour will come out. I did not use enough green so those chips did not work very well.

3| Lay chips out on your cooking tray and place in the oven to cook. How long you cook depends on what brand your chips are, so check the instructions on the packet. I cook my chips in the oven as it's more healthy etc I do not know if this will work in a deep fryer as it may take some of the colours away. Make sure you turn fries over midway so they don't burn.

4| Serve and Eat 

 I was amazed they worked as well as they did for the first time as I have not seen them done before so had no reference to work off.  I was also pleased they still turned out crispy. I was worried because I soaked them in the water they would stay soft but they did crisp up like normal.

I hope you have fun experimenting with this idea with some different colours. Let me know how you go if you try this.  I think these Rainbow French Fries are a good idea for a party or treat but I wouldn't do this to encourage your kids to eat if they are fussy eaters. Just because you don't want to be giving the kids colour additives all the time.
