My aunt, who is an avid bicyclist, told me the other day that after gazing at fields upon fields of chicory during her recent rides, she decided she wanted to try to make coffee with it. She remembers her parents drinking only chicory during the War, when coffee wasn't easily available. She has seen it for sale but only at gourmet shops at very high prices, which is what made her think of it. She has the impression there may be health benefits too.
She was assuming you brewed the leaves like tea. I told her I am pretty sure you have to dig up the roots and roast them, then maybe grind it up? Anyway it's not common around here, so hoping someone elsewhere can tell me what she needs to know. I myself would like to get into foraging, so this may be an easy place to start. Or maybe the wild stuff might not be the best idea?
