Here is a recipe we will be trying with the larger prawns. This recipe is from the owner/chef of the "Green Papaya" in Brisbane (who also happens to be the mother of Quan from Regurgitator for those who know what I am talking about...).
We ate this dish a few times at the Green Papaya in Brisbane, and it tasted great!
