**84** 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

- **Beef + Onion**: onions sweeten seared beef, philly style
- **Beef + Cheddar Cheese**: the cheeseburger pair: sharp on seared beef
- **Onion + Cheddar Cheese**: cheddar and onion, the ploughman's pair
- **Jalapeño + Cheddar Cheese**: jalapeno cheddar: green heat in sharp fat

## How to raise it

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