I made a Captain America shield for my son's birthday and I used the Americolor Red as I was told it didn't have a taste. My son wouldn't eat any of the cake with red icing because it didn't taste good. It was the same icing over the entire cake and he normally loves it (it's a white chocolate buttercream). I tried it and I have to agree with him, it didn't taste good. Did I do something wrong? Why did it change the taste?Any help would be appreciated, thank you.
