I've tried to search and find any older threads with no success -- does anyone have any recommendations for babyfood storage containers that they really liked?

I'm making LOs food and picked up a set of containers that I'm using but don't care too much for. They have too much space between the 2oz (max fill) mark and the top/lid so there's a lot of air and when I freeze them there are ice crystals on top of the food inside. Not that that's a big deal, I guess, but I also just don't really like them!

There seem to be so many out there, some pretty expensive, and before I invest in more I want to know I'm going to like them! Also, if you have an even better way to freeze/store baby food (ice cube trays?) let me in on the secret!
