Mayonnaise is usually a viscous liquid--well, unless you forget about it in the back of the refrigerator for a couple of years.
But you don't have to wait that long in order to eat it as a solid. Andrew Liszewski of Gizmodo informs us that in Japan, mayonnaise sometimes comes in slices akin to cheese shingles. You can drape a mayo slice onto a sandwich, noodles, or ice cream.
