Pick ONE room you know really well — like your living room. Now go clockwise from the door, and use each object in the room (bookshelf, sofa, coffee table, TV...) as an anchor.
For each anchor, create a bizarre, vivid interaction with the thing you want to remember. Not just "place it there" — make the anchor and the item interact in an absurd, sensory way. Weird = unforgettable.
You're in your living room. Go clockwise around 10 anchor objects. Each anchor has a wild, vivid interaction with a grocery item. Then recall them all from memory.
