title_body: Is it safe to consume roasted rice as a substitute for coffee beans?
upvoted_answer: While I never heard of rice as coffee-substitute, people have used roasted malted barley, spelt, chicory or dandelion roots or even acorns (and other foods) to make a dark, aromatic brew that was used either separately or mixed with coffee, especially in times of scant resources.
  I suppose the rice would not be burnt1 (because that would taste horrible), but roasted instead. Healthwise it is perfectly safe, like the other options mentioned above. Just note that rice has no caffeine, so you wouldn't get the &quot;kick&quot; you get from real coffee.
