Why doesn’t this exist?
Take dried beans, roast 'em, grind 'em, and brew some bean juice?
I have no idea if it would taste good or not, but we don’t know if we don’t try.
Edit: I need to see what dried beans I have and maybe go shopping. I will give this a try with a couple different types of beans and report back if I fart or not.
Just to piggyback on this. The simple truth is that lot of things are just called things because they resemble other things, either in form or function.
Coffee is not a bean; beans come from legumes, coffee fruit seeds are roughly bean sized and shaped.
Cacao and vanilla are also not legumes.
The peanut is a legume like beans and peas, but the it’s fruit treated like a culinary nut.
Cashews are not true nuts. They Grow outside the actual fruit.
Nut milk and butter do not come from mammary glands.
Tea is made for the leaves of the tea plant (Camellia sinensis), which is a shrub or small tree, but many infusions of dried plant matter are often referred to as teas. The Tea Tree (Melaleuca) of oil fame is a different plant entirely. It got its name because some sailors made a ‘tea’ from its leaves after they ran out of real tea leaves.
Currants (genus Ribes) are actually named after raisins. Raisins of Corinth were small raisins that were produced and exported from… well… Corinth. Over time ‘Corinth’ morphed into ‘currant’, they dropped the ‘raisins of’, and the local small dryable fruit started being referred to as a currants too. Eventually, production of the tiny raisins migrated to other parts of Greece and some smart guy thought “Hey! Let’s market these fancy tiny raisins that we are importing from Zante (the greek island Zakynthos) by calling them Zante Currants to distinguish them from the common local currants.
And many “flowers” are not flowers at all. Poinsettia is the first one that comes to mind, but there are lots of them.
