**72** Balance, out of 100

The seven flavor axes of the whole sandwich, each summed across its layers. The shaded ring is the catalog's middle 80%; the small number under each axis is where this sandwich falls in the catalog. A shape that sits inside the ring is in the range most sandwiches live in; a spike past it is where this one stands apart.

## What each layer brings

| Layer                              | Role    | Flavor and texture                | Points    |

Points: what the Sandwich Score would lose if that one layer were left out, everything else the same. A negative number means the sandwich scores higher without it. Flavor runs 0 to 5 on each axis.

## Pairings

- **Beef + Swiss Cheese**: roast beef and swiss, the deli melt

## How to raise it

Commodity bread (burger bun): nothing on the board changes that, and 90 is closed.
