Miniature Pies Baked in Canning Jars
My girls do something similar they recycle tuna cans and bake in them, cooling, placing ice cream, then freezing them for a summer treat. A lot cheaper than buying and you get your own flavor.
Reuse Hand Pumps
I also reuse handpumps for in the fridge. Lemon/lime juice, cooking oil, when you just want that dab in your food. NancyLC
