How does one cook with aloe? There is an asian grocery nearby and I've seen foot long lengths of aloe vera plant in the produce section.  I have an aloe plant at home. What do you suppose people do with aloe as a ingredient?
As Kruti Jani rightly pointed out, you can make aloe vera juice. Aloe vera gel (made like this) can also be diced finely and mixed into fruit juices to give a texture and slight freshness to a glass of juice. I have also seen it (the aloe vera gel) mixed with lemongrass jelly or mango sago dessert.
