How can I make purple popcorn in a movie theatre popper?
I've tried soaking the popcorn seed in dye for 18+ hours then letting them dry out completely, but that makes the kernels purple and the outside pinkish. I tried adding dye straight into the popper with the oil, but the dye isn't strong enough to overpower the yellow of the oil so it comes out a gross looking green. I don't have a million dollars to buy gallons of purple food coloring, so can anyone familiar with commercial popcorn machines think of anything? I have to figure this out by tomorrow night.
