My first bento box and its got blue rice. I’ve always been fascinated with how pretty bentos can be, but put off by the food coloring used to achieve some of those effects. Then I found this excellent tutorial at Eye Candy food blog on how to get a beautiful blue color using red cabbage of all things.
It’s actually pretty easy to do. Well, not as easy as pouring a few drops out of a little bottle from a store shelf, but still very easy and kinda fun too.
Basically, it’s just cooking shredded red cabbage in water. Drain, and you’ll see that the water turned a purple color. By adding an alkaline such as baking soda, it becomes blue! Add an acid like vinegar, it’ll be pink.
To minimize the cabbage flavor of the blue dye, I added a few tablespoons to just the amount of rice I wanted to turn blue. Mixed well and then poured out the excess liquid. Placed the blue rice in the fridge overnight. In the morning, it’s even bluer.
For the tofu fish, it’s just a couple pieces of Crispy Baked Tofu cut into a fish shape with barbecue sauce eyes. The underwater flora is blue lake green beans and the bottom is sliced raw carrots.
