This is Piaget’s conservation of volume test. I did this experiment at school (we went to the elementary school next door and ran tests on the kids). Most of the kids said the higher one held more liquid because it was ‘taller’, though some said the short one had more because it was ‘fatter’.

A further complication is that the aluminium is considerably thicker on the base and the top… so there’s more thin metal, and less thick metal.

Toasted ham and cheese with quality ingredients. It’s a tasty marriage of sweet sugar and salty ham, crisp toast and melty cheese.

Best one I made was when staying in Antwerp. I got the cheese in Amersdam - a truffle gouda. Butter was also dutch, from memory, but I can’t recall exactly. Nice and salty. Bread was local - Suikerbrood. Sweet bread that browns easily. Ham was prosciutto from France somewhere.

Have to put the butter on the outside and pan-fry slowly to ensure the cheese melts. The If you don’t have a sweet brioche bread, sprinkle sugar on the butter to get that crisp, sweet exterior.
