**80** 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

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 + Cheddar Cheese**: grilled cheese law: sharp cheese, tangy crust
- **Bacon + Egg**: the breakfast contract: smoke and yolk
- **Bacon + Cheddar Cheese**: bacon cheddar: smoke and sharp, burger law
- **Egg + Cheddar Cheese**: cheddar melts into soft egg, diner law
- **Egg + Mayonnaise**: egg salad core: yolk richness doubled

## How to raise it

- Judged as a breakfast: richness is not held against it.
- Between you and 90: balance 0.80 or better (0.14 short).
