Add reserved skins and trimmings from the onion, garlic and celery, with reserved rosemary stalks. Add the water and ½ cup (125ml) of the wine; bring to the boil. Skim any scum from the surface.

When corn is cool enough to handle, cut kernels from cobs. Add remaining oil to prawn meat, season; toss to combine. Cook prawns on heated grill plate for 3 minutes or until cooked.
