What do we learn from this? Almost nothing. Mostly, I just love thinking of the application layer as the coconut layer and the physical layer as the butter layer. But we may note that in food as in networking, it's the middle layers that are more-or-less optional. I mean, you can't have a ground beef casserole without the grated cheese, and a seven-layer bar without coconut on top is a different thing (admittedly, in some people's eyes, superior). But you can fiddle with those middle layers a bunch.

A note: I couldn't actually find any seven-layer cocktail recipes. This is a relatively classic six-layer pousse-café with cream on top. If you wish to create your own OSI model cocktail here is a list of specific gravities although I note that it disagrees with the recipe above about grenadine, which it thinks is lighter than Creme de Cassis. Alas, this probably depends a great deal on your grenadine and your Creme de Cassis. As a metaphor for networking, this is totally unenlightening.
