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.

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 + Pickle (cucumber)**: pickle brine against rich beef

- **Bacon + Lettuce**: cool crunch against hot smoke
- **Bacon + Tomato**: smoke against sweet acid, the blt core
- **Mayonnaise + Tomato**: summer tomato sandwich: acid on rich

## How to raise it

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