Carambole

Oxalic acid tastes metallic on its own; citric acid pushes it toward clean sour.

Heat over thin acid gives the slices a second sensation to carry on the tongue.

Caramel takes the metallic edge off and turns a sharp fruit into a dressing base.

Green aldehydes match the green acid; both are bright and neither is deep.

Gingerol warmth against cold sour water. Without it the plate is one flat note.

Salt suppresses the bitter oxalate and lets the sourness through unclouded.

Glutamate and funk under raw acid is the whole Southeast Asian salad structure.

Sweet shellfish needs acid, and these slices bring crunch a lime wedge cannot.

Fermented marine funk against sharp fruit is the Malay rojak dressing exactly.

Earthy bitter root gives a very thin sour fruit a floor to stand on in a sour curry.

Oily fish and oxalic acid: sharper than lemon, and the slices hold their shape.

Juniper resin and green acid dry the mouth together; the fruit becomes a garnish that works.
