You know those modern tin-openers that run on batteries and not muscle? Well, I have one and I've found that it de-sharpens the edges of tin lids so well that I can use the lids as individual palette thingies for mixing watercolour paint.
I love finding out stuff like this 🎨🖌🖼👩🏻🎨
We don't use many tins but MrB bought some early on in the pandemic in case we had to isolate for a few weeks ever (we didn't) and I'm just using them up now – evaporated milk today that I'm using in an eggy macaroni cheese recipe.
Eggy macaroni cheese was brought up on another GN thread recently. I'm glad to have a use for the evaporated milk he bought.
