There is a horse cupcake recipe out there with white Circus Peanuts. Do you know of anyone in the Cedarburg, WI (@20 miles north of Milwaukee) area that might sell them?
Here in New England, it's high season for Circus Peanuts, so you can usually find the mixed bags, but I'm not sure about the Midwest. So.... anyone have an answer?
(FYI: You can see these cute cupcakes at http://www.hellocupcakebook.com/, and they also have a list of mail order places to get the white peanuts.)
