I just had an idea for you mush makers out there
if you go to a hobby store and look in the paint section, you'll find little plastic trays for a buck or so that have little dimples in them. The dimples are about 1/2-1" and usualy about 15-20 on a tray.
buy 10 trays. make your mush. pour the mush into the trays. put the trays in the freezer. when they're frozen, pop out your pre-measured mush lumps and feed as desired! (you could even pop them out ahead of time and put them in a baggie to save space in your freezer)
what'd ya think?
