Original Purpose: Dressing French fries.
Aha! Use: Decorating dishes like a professional. Run an empty plastic ketchup bottle through the dishwasher (or pick up a fresh one at the Container Store; $1, www.containerstore.com), then fill it with your favorite sauce or condiment. Drizzle some rosemary-scented olive oil across a bowl of white bean soup, a squiggle of fudge or raspberry sauce around the rim of your Valentine's dessert plate. (If calligraphy is not your strong suit, practice on a paper plate or stick to abstract designs.)
Reward: Five-star-chef presentation in less than five minutes.
Other Use: Fill with a week's worth of homemade salad dressing and squirt as needed.
