Christmas Down Under falls in the middle of summer and is often celebrated on the beach with the holiday feast cooked on the “barbie.” Prawns, steaks, chicken, and lobster, as well as fish, are all popular entree choices to be cooked on the grill. Barramundi is a white-fleshed fish popular in Australia but seldom found outside the country, but other fish such as cod or swordfish can be substituted.
