Can't find original thread so here goes

[decadence]

Can't find original thread where this post should go so I have to start a new thread to ask the question. I used the search function but couldn't find it - it was far from controversial

A while back I asked about smoothie recipes and everyone was really helpful. One person near the top of the thread posted some links to some recipes (on a military site I think); it might have been docetboy but I'm not sure?

Anyway, the recipe stipulated "one spoon of vanilla" (think it was that amount from memory). It might sound like a stupid question but I wanted to know if anyone knew if they mean vanilla ice cream, powdered vanilla pods, vanilla essence or what?
Thanks.
