Rule one: Never reheat more than once. You get one shot. Reheated leftovers of reheated leftovers is a biohazard you don’t want to explore. Rule two: Eat them within a day or two of cooking. Prawns don’t age like fine wine; they age like milk in a hot car. Rule three: If they smell even slightly “off,” like a gym sock that met the ocean, throw them away. Your tastebuds will thank you, and you won’t spend the next 24 hours hugging a toilet.
You’ve got this. Go forth, reheat your prawns with confidence, and remember: a warm prawn is a happy prawn. And a happy prawn makes for a happy you. Just don’t use the microwave. We’ve talked about this.
