Dragging around propane for a grilled cheese is one of those levels of dedication that either receives loathing or respect. I'm of the ghee/butter camp myself, but I've never tried duck fat, so I should get around to that. I have had duck eggs before and those blew my chicken-egg-eating mind, duck really just means "chicken on steroids." You absolutely must do the biscuits, maybe fry up an entire breakfast with it and then go get your cholesterol checked. Quinoa has more of a "nutty" flavor, I used to be vegan for a while and made a point of trying every grain possible and it scores high on the woo woo scale cause its got more protein than others and DAT dietary fiber most people are lackin. I don't remember much about amaranth, but I think it tasted funny.
Haha, "tasted funny" is not exactly the lasting impression that makes me want to try new foods, but I'd still give it a shot. Now that I think of it, I've got some duck stock from the same bird, so I could also make gravy. Biscuits and gravy it is. Some days I regret learning how to make biscuits and gravy, but it does give me a real motivation to exercise!
