Ever wanted to make Maangchi's Rainbow rice cake but went all around in search for frozen rice flour needed for the recipe and ended up with only dry rice flour? Haha don't worry! you're not alone ;) that happened to me too! And I'm sure alot of others as well!
I decided to search for substitutes and came across http://www.maangchi.com/talk/topic/how-to-make-rainbow-rice-cake-with-dry-rice-flour
Indeed it was helpful! However it did not say what is meant by a "dough". So I decided to experiment a bit!
I ended up with the finish product shown here:
(Hehe, I decided to have some fun while eating it)
So basically, you need to make your own frozen rice flour!
10cups of flour (you'll find there will be some left over which you can store in the freezer and use later)with water*
*Amount of water varies, you need enough water for the flour to pack together when firmly clasped between your hand but still able to break apart with a light tap
as shown in 6:57 in maangchi's video
Too dry?-Put more water!
Too wet?-Put more flour!
Then put it in the freezer at least overnight and then follow maangchi's recipe for method and amount of dry ingredients,I used the "firmly clasp and tap" method to figure out the amount of wet ingredients.
If you want the colour for your rainbow to be more intense, add more colouring but less water!(Applies if you're using liquid food colouring, gel food colouring shouldn't water down your product) :)
Have fun with your rainbow creations! :)
