nick2003,
If this is the Nostalgia that is a hot air popper, I cannot help you. It'll only pop the corn with no color or flavor. If it is the kettle popper with the crank, you might be in business...
To get the color, you need the regular oil popper. The color comes from a combination of Flavocal (very fine orange colored salt) and coconut oil (also colored as well). A lot of us purchase Mega Pop popcorn prepacks, where the corn, Flavocal, and oil are all premeasured into a single pack. I get mine from my local Gold Medal popcorn distributor . There are other places to get it - just do a search. Now you may have a problem with the prepacks. If you have the 2 oz model, the prepacks won't work because they only make 6 oz packs and larger. YOu would have to mix your own. Still not a huge problem. Sam's Club sells the Flavocal and the coconut oil. You just have to read the directions and do the math - then tweek it to your taste.
