Y'know, I have a big squeeze bottle of ketchup sitting in the fridge unopened. Several times I have thought, "this dinner could use a squirt of ketchup to dip into." But because it's just me, and I only ever use a little squirt, I always decide it's not worth starting the clock on that big jug. Probably silly because ketchup is famously long-lived, but better for me not to get all that sugar in my system anyway. Sometime when the kids are all home I'll have to plan a dinner that justifies breaking the seal.
