My favorite "food porn" are sub sandwiches. Nothing can go from looking "gone" to over three feet long like a sub. Just don't let your friends sample when it's fully "expanded" or you'll tell them to fuck off for eating too much.
Oh, as for leftovers, does it really matter when it's from? I cook with bacon fat and butter everyday anyway so everything tastes good!!!
Heart attack, here I come!!!!!!!!!!!!
