What's the difference between carob powder, flour, and kibbled carob?
Almost 90% of the carob is pulp, and the rest is the seeds. From the seeds, you get Locust Bean Gum, or Carob Gum.

The pulp can be used either as:

Carob Powder/Carob Flour, which has sweet and chocolate-like taste. 

Carob Kibble, which is basically much coarser pieces of the pulp.

Carob Syrup, if you extract the sugar from the pods, you get the syrup.
