Congrats, experimental dinners are not to be scoffed at (scoffed down yes)
My favourite for oven / grill finishing any meat is to use an “X” rack (stainles steel) which allows better air flow crisping on all aspects of the bird & more meat gleaned & consumed
Duck has produced favourable results this way.
Searing is one of those things that experience calms the feeling of pressure & screwing up.
Butter caramelises meats nicely, my preference working on good pan finished colour without too much hang time in the pan (I force myself to use alexa timer as a guide)
