Your tea infuser can be used for a lot more than just tea. How about using it as a bouquet garni sachet the next time you make soup?
The habit really surfaced out of desperation one day as I was making a pot of split pea soup. A bundle of thyme, bay leaves, and peppercorns was called for, secured in a cheesecloth pouch. Without any cheesecloth on hand, I scoured the kitchen drawers and came up with my little-used SwissGold tea infuser. I filled it with the soup's seasonings and clipped the little chain to the side of the soup pot. It worked like a charm to infuse not a cup of tea but a delicious pot of soup. So I didn't rush out to buy cheesecloth: I've used the infuser solely for soups ever since.
Do you repurpose tools in your kitchen in moments of desperation? Have you hit upon any happy accidents that are now routine?
