'''Dandelion 'coffee'''' (also '''dandelion tea''') is [[herbal tea]] used as a [[coffee substitute]], made from the root of the [[Taraxacum|dandelion]] plant. The roasted dandelion root pieces and the beverage have some resemblance to [[coffee]] in appearance and taste.

==Harvesting==
[[File:Roasted dandelion root.jpg|thumb|Roasted dandelion root, ready to be used to prepare dandelion coffee.]]
Harvesting dandelion roots requires differentiating 'true' dandelions (''[[Taraxacum]]'' spp.) from other yellow daisy-like flowers such as [[Hypochaeris|catsear]] and [[Crepis|hawksbeard]]. True dandelions have a ground-level [[Rosette (botany)|rosette]] of deep-toothed leaves and hollow straw-like stems. Large plants that are 3–4 years old, with taproots approximately 0.5 inch (13 mm) in diameter, are harvested for dandelion coffee. These taproots are similar in appearance to pale [[carrot]]s.
==Preparation==
After harvesting, the dandelion roots are [[Drying (food)|dried]], chopped, and [[roasting|roasted]]. They are then ground into granules which are [[steeping|steeped]] in boiling water to produce dandelion coffee.<ref name=naturenet>{{cite web|last=D’Alessandro|first=Ruth|title=Naturenet: Costa Coffee?
