Friend-baker cleaned closets and gave me a bag with expired chocalate cake mix.
Is it OK to add it to compost or dig into soil?
The flour mixture might attract rodents, especially if it "cakes" up...that said, if it's not an issue it should be fine if the rest of the mixture isn't too high in fats that would become available once moist.
The carbs would feed fungi and the sugars would feed microorganisms.
Mix it in well to avoid caking and rodent attractiveness...apply appropriate or sparingly depending on the size of your pile, how "hot" it is, and how quickly it can "work on" the amendment.
I just baked some pre-packaged cookie dough, ten years old, last week. It worked fine.
How old is it?
The "use by" and "sell by" dates found on food products are meant to help the retailer keep moving stock. They are not meant to tell you that food is no good after then.
If theat mix does not have weevil larva crawling around in it it can probably still be used, however, it can be composted just as any other food you could eat can be.
Here is a link that might be useful: Use by dates
I wouldn't put it where a dog might eat it. I seem to remember that dogs don't do chocolate?
Thank you for that link, I greatly appreciate it.
I helped someone clean out some kitchen cabinets of long-expired food last year and composted all of it, about 2 boxfuls: plant-protein powders, boxed soups and soymilks, unidentified grains, etc. I mixed it a little with browns (mulch) as I added it, but it was still a pretty disgusting process. And then, a couple months later, I moved all my compost bins AND the compost. That bin was the stinkiest compost ever! As I moved it, I distributed the stinkiest glop to different bins and made sure to put lots of normal compostables and mulch between layers of glop.
And when the compost was done, I couldn't tell the difference between the bins that had the pantry glop and the bins that didn't. It was all great compost!
