Overcooking prawns is a sin if you're religious or a crime if you're not. Either way, don't overcook your prawns. Nothing should ever be overcooked. Even if you fear a deadly food borne disease, there are ways to render food safe without overcooking it. While I'm on the topic of rendering food safe, you know, I get the whole raw dairy thing in terms of enhanced flavour and taste, but with monotonous regularity (almost as regular as my bowel movements) I read reports from around the world of foolish people sharing or worse selling dairy products that have not been made safe by using pasteurised milk. Raw milk is dangerous people. The only time I'd drink raw milk is if my mouth was within a few centimetres or attached to an actual mammal's nipple. Granted, farmers who know what they're doing who milk a cow and immediately put some milk in a container in the refrigerator have about a 24-hour window to enjoy wholesome fresh unpasteurised and unhomogenised milk.
Serve the prawns on some spinach leaves. Spinach leaves are a bit of a bugger if you want regular bowel movements. Spinach and some other leafy green vegetables have a lot of iron and it makes your stools go black and sticky. I've increased my intake of Chinese gooseberry to help with the consistency of my faeces.
