coffee: a beverage made by percolation, infusion, or decoction from the roasted and ground seeds of a coffee plant
I wondered, "If coffee is made from, well, coffee beans, why not make it from peanuts? Or pistachios, or lentils, or peppercorn?" If coffee is made from roasting the pit of a specific type of cherry to the desired level, grinding it to a desired level of coarseness, and then running hot water over it, it seems to me that most other seeds, legumes, nuts, etc. can undergo the same magical operation.
Lo and behold: peanut coffee. However, this is the only coffee alternative I found. I have found the existence of drinks infused with flavors such as pistachio-infused coffee, or the infamous pumpkin spice latte, but I have yet to find a drink brewed from anything other than roasted coffee pits or roasted peanuts.
Is it possible to use the coffee brewing method on other foods and yet preserve/enhance the food's flavor, creating a drink?
I don't need to know whether we can roast similar foods to open up a new world of coffee since I already know we can.
But what about foods other than the before mention types? To specify, any food that isn't a seed, pit, nut, legume, or anything similar to those. Can we roast, grind, and brew other foods to concoct a previously unforeseen beverage?
With something like banana chips, I believe the natural coating of sugar would prevent the water from effectively absorbing flavor. What about vegetables?
What about meat? It should be known to many that charring food actually enhances its flavor. But, as I have learned in researching this, there is a cancer risk in charred meat. So, are there other ways we can extract the flavor from meat to make some kind of weird meat coffee? And of course, do this abiding by the traditional process of brewing coffee, or else this question wouldn't belong here.
I believe my question is more of a chemistry question, however, it doesn't belong on the Chem Stack (to my knowledge, although I'm likely wrong here).
To show what I mean by this here is an overly shortened example of the kind of answer I would expect:
No, you cannot. Due to [insert chemical reaction], the food would effectively turn into poison.
