I totally forgot about ghee despite having a tub in the fridge, and using it last time I cooked a steak lol. Good shout. It adds a nice nutty flavour if I recall
But butter is only for finishing, to bring out the garlic and thyme flavours. I cook it with a bit of oil if I finish with butter
Coffee is mostly ingredient however. Good luck doing a good coffee with poorly roasted or stale beans while fresh beans will give you a proper cup using a press even if you do it extremely poorly (in so much as you can even mess up a press).
