In a medium saucepan, combine olive oil, cloves, water, white wine, onion slices, carrot slices, lemon slice, parsley sprigs, dried thyme, bay leaf, dried red chile pepper, peppercorns, and a pinch of salt.

Bring the mixture to a boil over high heat, then reduce the heat to low and simmer for about 10 minutes.

Add the langostinos/prawns to the simmering liquid, return to a gentle boil, and cook until the langostinos/prawns turn pink, approximately 2 to 3 minutes.

Remove the langostinos/prawns, keeping the cooking liquid.

Peel the langostinos/prawns and place them in a medium bowl.

Bring the reserved cooking liquid to a boil over high heat and let it cook until reduced by half.

Allow the liquid to cool.

Discard the bay leaf, then pour the reduced liquid over the langostinos/prawns, stirring to coat evenly.

Cover the bowl and refrigerate for at least 24 hours.

Serve the zesty citrus-marinated langostinos/prawns cold for a refreshing culinary experience.
