BarmyFotheringayPhipps found some silicone ice cube trays in a kitchen goods store while I was getting my hair cut this afternoon. He refrained from buying a couple because they were rather pricy ($12 each), but we're in the market for some new trays because the cheap ones we bought recently aren't as good as they might be. Has anyone else here used silicone ice cube trays? Are they worth the premium price? Thanks!
