I got that idea from an old Reader’s Digest story from decades ago.
A college student living in a dorm was upset that every time she bought some ice cream on her meager allowance and put it in the dorm freezer, someone would invariably eat it.
So she got the idea of putting it in a brown bag and labelling it “TOFU” and nobody ever touched it again!...............
Great story! I love banana ice cream but family hates it - why I always buy it, otherwise it is gone. Learned to put horseradish on my sandwiches - otherwise my lunch is eaten the night before I’d go to work.
