Julia has been experimenting! Here's what she had to say...
"I made some MMF color samples and thought I'd share my results. The black weighed in at 3 pounds 5.5 ounces so I imagine they're all about that weight. I did forget to say the black has about 1/4-1/2 cup of dark cocoa powder + rest PS to = 2 lb to help assist with the black color (and chocolatey taste)."
Here's enlarged text from the picture:
Julia bought her food color from Restaurant Depot.
We may need to make a field trip there with her!
Have fun experimenting!
And thanks Julia for sharing your results!
