Ditto Catrin - refined (cold pressed) coconut oil is flavorless (and odorless). The unrefined stuff tastes like coconut and I really only like that flavor in sweet things, so I don't use it much.

I also cook with clarified butter (less flavor than ghee - it tastes like butter), good bacon fat (only from known-source, ethically raised, sugar and nitrate free bacon) and olive oil. Olive oil is fine if you aren't frying in it (ie, not super high heat).
