I'm not sure if anyone is here from the reddit community, or remembers my tiny post about trying to find a way to package my dog food without using ziplock bags.
But basically, I said I make my dog food in bulk, using vegetables that where dumpsterd, home grown, etc. At the time I had a 150 lb cane Corso, only. So portions where already pretty large, I would process and freeze vegetables as needed and make a batch of dog food all at once in a 30 ish gallon stock pot, then freeze them in flat packs of ziplocks.
Since then I also have an incredibly high energy rescue pit mix puppy in my family.
I was given allot of advice, all of which I tried out.
The one that I thought would be the most promising was freezing them in sheet pan trays, scoring them. And separating them with wax paper.
No lie. This worked horrible. I tried many iterations of that. Nothing worked out.
I did end up finding a solution.
I found large plastic Tupperware containers. They're about the size of casserole dishes. Just twice as deep. I fill those and pull 2 out at a time one to defrost on the porch and the other one to throw in the fridge for a few days. By the time the first one thaws out, the one in the fridge is about kicked. These containers are pretty cheap. And I don't expect them to last forever. But I'm very careful with them and so far it works great! I should also say they seem to hold up longer than the reusable vinyl/silicone bags I tried. Tbh for most applications, I would recommend using Mason jars over them for pretty much everything.
I was so hesitant to buy plastic Tupperware that I ended up creating more waste in the long term.
