My broth/stock hack is to just get a bulk canister of dehydrated stock powder marketed to restaurants, you can find perfectly acceptable quality-wise for any use at home and its consistent. I do save things for making soups but come on… you’re not gonna get a quantity that’s worth all the effort if you’re just going through the food you’d eat at home. These ingredients how they’re used today were basically invented through restaurant processes where you have large quantities of ingredients and importantly, meat scraps like trimmings bones and carcasses coming through daily on a predictable schedule.
