This is how we got the yogurt bites in cereal, they reused the cereal crumbs at bottoms of ovens instead of trashing them
Any more food products you know of which use leftovers? I’ve always suspected jam and juice to be high in leftover content.
I suspect, if not leftover, certainly rejected (for visual appeal if nothing else) fruit is used in this way. Just as commercially sold 'baby' carrots are produced from ugly carrots.
Tater tots were originally made in effort to save potato scraps.
Wow, rejected cornflakes? I didn't know that anybody bothered to inspect them. Must be a tedious job.
