To boil: Bring a saucepan of water to the boil and add the prawns. Once the water returns to the boil, cook for 2 - 3 minutes, then remove promptly, rinse to cool them and use them in your favourite recipes.
To pan fry: Toss or rub the prawns with a seasoning mix. I usually use a combination of sea salt, paprika, red pepper flakes, and dried oregano. Heat butter or oil in a skillet over medium heat. When hot, add the prawns. They should sizzle right away. Cook for 2 - 3 minutes per side, flipping only once. Remove from the pan and transfer to your serving dish or add to a bowl of pasta or rice.
To stir-fry: Heat your skillet or wok, cook the shrimp first, then remove and keep warm while you stir-fry the rest of the vegetables in your recipe. Add the shrimp back in to the skillet or wok, then thicken the sauce, if necessary.
To grill: Skewering shrimp or prawns is the best way to grill them, to prevent them from falling through the grate. If you're using wooden or bamboo skewers, remember to soak them in water for at least thirty minutes before skewering to prevent flare-ups.You can marinate them beforehand in a simple marinade of olive oil, lemon, garlic and herbs, or brush them with a sauce, or simply brush them with a little oil or butter and serve with a flavourful dipping sauce. They only need 2 - 3 minutes per side, depending on their size. You'll know they're done when they turn pink and lose their translucence.If you don't want to use your outdoor grill, an indoor grill pan works beautifully too. You can also put them under the broiler to cook.
To air fry: Shrimp and prawns cook very quickly in an air fryer. After cleaning, you can cook them from frozen, bread them to serve with a dip, or toss them with oil and a seasoning mix.
