Hassaku
Citrus hassaku · Citrus
40 pairings
The hassaku is a large, firm, pleasantly bitter Japanese citrus — a natural pomelo hybrid the size of a small grapefruit, eaten segment by segment rather than juiced. Under a thick, knobbly pale-yellow to orange rind sit big, coarse-jacketed segments whose flesh is crisp and separates into distinct juice sacs, tasting fresh, lightly sweet and bracingly bitter with a clean, slightly sour edge — a springtime eating citrus prized in Japan for its firm bite and refreshing bitterness rather than for sweetness.

Keeping ittap a band
A domestic fridge holds it about 3× longer than the counter.
Humidity
90–95%
Dry air is what pits this rind: at 75–80% it browns over the oil glands within a month of harvest, while 90–95% largely stops it. Keep it damp, not draughty.
Airflow
Bagged, not open
Unlike most citrus it keeps better wrapped: a poly bag or film sleeve holds the rind moisture that stops the pitting. Fold the top over rather than knotting it.
It answers to other fruit's ethylene
It makes almost none itself, but like other citrus it answers to it: shut in with apples or bananas the calyx browns and drops, letting rot in at the scar.
