Can I just put a word in for cold smoked butter? Although I do a lot of cheese, by request from friends, the standout dairy to smoke for me is butter. It can then be used to introduce a subtle smoke flavour to anything you cook with it, including melting on baked potatoes.
Absolutely awesome is scrambled eggs made with smoked butter.
As I eat/drink mainly goat dairy produce, the butter I use is usually in stick format so convenient for smoking. If you are using a standard block of cow's butter, I would cut it in half lengthways, to increase the surface area.
Best smoked in cold weather, for obvuous reasons. Best wood (in my opinion) is oak, although I also have done maple. I usually open out the wrapper it came on and arrange the butter on that, rather than directly on a grate, as even in cold weather, it can start to sink through otherwise.
