To get the great chickory taste... It's necessary to roast the root first... Grinding is optional.
I've done it, but... I can't grow chickory in my garden. Voles eat it.
I had some growing in my previous garden, I could barely keep it alive in the GA heat. Plus... I had voles there too.
I'll bet someone could gather seed and work out some good trades...
The seed are very easy to collect.
