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    |
| ------------------------------------ | ------- | -------------------------------- | --------- |
| grilled rye breadscored as Rye Bread | bread   | bitter 2 soft crusty             | the frame |
| 1/3 lb beef pattyscored as Beef      | protein | fat 3 umami 3 juicy chewy tender | **+18**   |
| swiss cheese                         | protein | fat 3 umami 3 salt 2 soft melty  | **+20**   |
| grilled onionsscored as Onion        | texture | sweet 2 crunchy juicy fresh      | **+13**   |

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
- **Beef + Onion**: onions sweeten seared beef, philly style

## How to raise it

- Between you and 90: balance 0.80 or better (0.09 short).
