Nothing dampens French fry-related enthusiasm more quickly than a clogged sauce bottle. Beating the bottle into submission works about half the time, but to really get things flowing again, you need to introduce a little air. Real Simple shows us how using a tool available at near every diner: a plastic straw.
Push the straw to the bottom of the bottle, give it a little shake, and — leaving the straw in the bottle — pour the ketchup with ease and grace. You are now free to eat your delicious fries with sweet and salty ketchup. (Unless you're one of those weirdos who hates condiments, in which case please leave, we don't take kindly to your type around here.)
