17 Apr Leak-Proof Ice Cube Tray
I have had numerous requests from people looking for a leak-proof horizontal ice cube tray, and I never knew of one. The ones with snap-on lids just aren’t secure enough for use on a boat — water (until it’s solid) will still slosh out with the motion of the boat.
- It will take a little longer to freeze solid than in metal trays, as the thick plastic insulates the water.
- They have to sit fairly flat or you’ll get a solid block at one end. You cannot use them as vertical ice cube trays.
- Be sure to leave plenty of airspace as the water will expand as it freezes (the air will condense; if there is too little air space, the plastic will crack).
For this to work, you have to use the egg cartons with the gasket and the locking lid. The Coleman “camping egg carton” is not leak-proof and won’t work!
The Lock & Lock Egg Cartons come in three sizes and are available on Amazon (sometimes available other places, but not consistently):
As a side note, I also love these for my eggs . . . they really protect them from breakage, and in the unlikely event that an egg does break, the mess is totally contained. Read my article on why I like them best for eggs.
