The bacon fat thread got me thinking. For years my Big Three were butter, EVOO and peanut oil. Tried several fashionable oils: Walnut (goes rancid as soon as you open it), grapeseed (fine but not worth the cost), pumpkin (forgot that I don't _like_ the taste of pumpkin), none of them stuck. Lately I have been getting more, um, animalistic. Duck fat is the new necessity, bacon fat is for more than cast iron seasoning, and I am considering ordering a batch of rendered leaf lard. What are your favorite fats/oils and how has your taste evolved?
