The commercial goop is garbage. It's sticky, a ridiculous red color, and outrageously expensive! My mom and dad figured out a perfect recipe decades ago, so I made up a batch tonight.
Simple supply list: I had an empty gallon orange juice container that I cleaned out, a large saucepan, and good old white, granulated sugar. Yup, no food coloring necessary once the little guys have found your location!
Bring a half gallon of tap water to a boil with four cups of granulated sugar, stirring occasionally to make all the sugar dissolve. When the solution becomes clear, turn off the heat and let it cool. I only boil a half gallon of water with the full amount of sugar for ease in refilling the jug. When the solution is cool enough to handle safely, pour it into the jug with the remaining water, cap tightly and shake to reach the proper dilution. That's it! Just refrigerate and pour into feeder when needed. You may want to occasionally shake the jug if your solution starts to crystallize back out, or you can simply boil it all again.
Enjoy your bird show!
