New uses for mason jar lids from Real Simple Magazine, February, 2017:
The outer ring parts to mason jar lids can be used as a makeshift muffin tin. You set six rings ,wide side down, on a baking sheet and place paper muffin/cupcake papers in each and fill with the muffin batter.
"Cant't find the muffin tin?" But here are these six jar lids just laying around so no problem.
This is not a kitchen I can even comprehend.
