Australians call them prawns. And I have never tossed one on the barbie.
We had a picnic in the park with vegetables and fried eggs. Then we had ice cream at the beach. Then later the kids had Burgers. I had some nice pate and dips to snack on. We are in the middle of a road trip and it was 35 Celsius today. Heading for 41 on Thursday.
Over here in shrimp country they have a size grading system, where the number of shrimp it takes to make a full pound is the grade.
Fifties and sixties are most common from the Gulf Of Mexico. Twenties and thirties are the most desirable for the frying trade and using on the grilles.
Once you get into the ten and eights, we are talking about more expensive shrimp, which might also qualify as prawns, whereas some of the smaller ones might not.
At "Black Beard's Restaurant" located on South Padre Island, near where I graduated high school, their house specialty was a choice between a two or a one butterlied, slathered in butter and garlic, various herbs, and grilled up shrimp. That means either a half pound or a full pound sized shrimp or prawn. You could also order a .5 (two pound shrimp) at times when they were available in the fall.
I love shrimp and even love those prawns which sport a weaponized funny accent.
