Each bar is one pillar of the score, 0 to 100\. The tick marks what a sandwich at the summit needs; an amber bar is the one holding this sandwich back.

**grilled sourdough**, toasted: over-hard egg; hash browns (low tier); american cheese (low tier); choice of meat.

Much of this build is inferred from the name; the score is a reading, and it stays out of Digger's Diner's typical score.

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 sourdoughscored as Sourdough | bread   | soft chewy crusty                       | the frame  |
| over-hard eggscored as Egg           | protein | fat 3 umami 2 soft creamy springy       | **+18**    |
| hash browns (low tier)               | bulk    | fat 3 salt 2 crispy soft fried          | **−4**     |

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

- **Sourdough + American Cheese**: grilled cheese law: melted cheese, tangy crust
- **Egg + American Cheese**: diner law: american melts into soft egg

## How to raise it

- Judged as an egg and cheese: richness is not held against it.
