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

- **Mayonnaise + Egg**: egg salad core: yolk richness doubled
- **Mayonnaise + Tomato**: summer tomato sandwich: acid on rich
- **Egg + Avocado**: avocado toast law: green fat under soft egg

## How to raise it

- Outstanding, not legendary: the menu does not name its bread.
