Leak-Proof Ice Cube Tray

Lock-&-Lock-egg-carton 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.

And then Victoria (see her blog, ForgeOver) told me her brilliant solution: Lock & Lock Egg Cartons!  Fill them a little over half full of water, put the lid on and freeze.  A few notes:

  • 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!

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.  See the Lock & Lock Egg Cartons on Amazon or read my article on why I like them best for eggs.

    A few months ago we went to the Seattle Boat show and we were thrilled to find a great vendor there called Get Storganized. We were able to buy lots of organizing stuff, egg cartons as mentioned above and …. a sealed lock and lock type ice cube tray which could be used vertically too. Once the lid comes off the first time it is hard to align things up again, as it was filled full, then expanded when it forze, but it doesn’t really matter because you can put it back in as is since the cubes you didn’t use are now frozen…or you can do what I do and dump the contents into a ziplock bag and fill it up again, to make more ice! (You can always use more ice!)

    We highly recommend their products and they have some seriously great ideas.

    Definately check them out.


  4. Hi Carolyn,
    I recently found this Joie spill proof ice cube tray at Bed Bath & Beyond. I bought one and plan to try it out. I like that it has a “Tupperware” type lid plus an opening to add the water.

    I have purchased a number of Lock-n-Lock products, including the egg containers (fantastic!!) based upon your recommendations but it seems there have been some changes at Lock-n-Lock over the last few months. I subscribed to their newsletter a while ago and recently received emails regarding a change in distribution channels and products. Seems they have dramatically reduced their product line and one of the products discontinued is the egg carrier. Their “classic” line only includes 17 products now – http://locknlock-usa.com/index.php?route=product/category&path=61_69&limit=100
