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

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

## How to raise it

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