For a more flavorful curry, you can marinate the prawns in the spice mixture for 30 minutes before cooking.
 If you don't have a pressure cooker, you can cook the curry in a regular pot. However, it will take longer, about 30-40 minutes.
 You can also add other vegetables to the curry, such as potatoes, carrots, or peas.
 Prawn Curry can be made ahead of time and stored in the refrigerator for up to 3 days. Reheat it gently over low heat before serving.
