grape nuts are actually an interesting solution to the problem of soggy cereal. they are basically inedibly hard unless you soak them in milk, at which point they soften enough to be chewable. I’m not even sure if it is possible to make grape nuts soggy lol. if so I feel like it would take quite some time

grape nuts are what happens when you put hard tack in a coffee grinder. that’s not an exaggeration or a joke that is actually how they were originally made

How do we pack all that goodness into those crunchy little nuggets? Originally, C. W. Post prepared a batter that came out of the oven as a rigid sheet. He then broke the sheet into pieces and ran them through a coffee grinder to produce the “nut”-sized nuggets.
