When reviewing vegetarian and vegan cookbooks, it is very common to see desserts prepared with agar-agar. Aside from pâte de fruits, I have never seen a dessert recipe call for pectin. In my own experience, I have found low-methoxy pectin (such as Pomona's Universal Pectin) to be far more versatile. It can gel quite stiffly if desired. I have found it to be preferable in every situation.
As such, I find myself perplexed as to why its use seems limited to jams and pâte de fruits. I can't find any evidence that regularly eating high concentrations of pectin is problematic; as a dietary fiber, the opposite seems true.
So the question is: why is agar-agar so much more prevalent in dessert recipes?
