Freezer tray ideas for home-made food ?

[kien]

I use these:



As Michika has already suggested, they are Ikea silicone ice cube trays. I like them because they are flexible so they can easily sit pretty much anything in the freezer. The fish food/mush is typically thick enough that it doesn't dribble all over the place. It's easy to extract the portions and each cube is the shape of a fishy!!
