Sudachi

The acid holds the pine up while the zest oil doubles it. Autumn Japan, in a lidded pot.

Buckwheat is nutty and flat. Whole slices float on the broth and season by smell.

Oily fish and green acid; the herbal edge does what a lemon cannot reach.

Salt holds a very volatile acid in place long enough to taste it twice.

Vinegared starch already has acid; the citrus adds only the green top note.

Glutamate under sharpness. The broth stops tasting brown and starts tasting alive.

Sharper and greener than lemon, and it stops before perfume.

Perilla aldehyde and green peel are the same herbal register, doubled.

Smoked inosinate needs a citrus with no sugar in it at all. This is that citrus.

Green acid over brine; sharper than lemon and it leaves nothing behind.

Juniper resin and unripe peel; the drink tastes like it was made in a forest.

Sharper and greener than yuzu; matches the grassy note exactly.

Catechin bitterness plus green acid. Cold-brewed, it reads as one ingredient.

Two green bitternesses, one Mediterranean, one Japanese. Neither blinks.
