All of a sudden the useful life of our ice-cube trays is ending, one by one. Those old metal ones with the lifter never wore out, but these twist'em ones certainly do. Since this is a household without air-conditioning in a not-cool climate, it's needless to say that our trays get real use. This week they're all going to tray heaven, it seems. A search on Google yields results that differ as between "ice trays" and "ice cube trays." I couldn't resist visiting the Tacky Living domain, which marveled at the existence of Texas-shaped ice cubes. Some of us are not at all surprised; we know that there are many sources for these things. One is My Texas Store, which also sells something called "mesquite clocks." . Another tidbit turned up is that somebody is selling old manuals and accessories, including ice-cube trays, under the Frigidaire name, complete with the original logotype.
