In Asis, people have to get pretty creative in how to use what little food is left, most of this involves ways to make use of otherwise inedible plants. No one really buys food based on how good it tastes, but rather on how well it will keep you going for a few days.  Drinks on the other hand are what people produce for enjoyment. Local teas are the most common and popular drink, easy to transport and store, along with easy to make even traveling. The flavor is similar to Rooibos tea. And who doesn't love alcohol right? The next popular drink a basic fermented root liquor that has many names, usually 'Rain Water'.
