| Temperature | Vinegar | Result | Fix |
|---|---|---|---|
| Fresh off heat (>40°C) | vinegar will not take | grains sticky, will not hold shape | cook 2h ahead, do not rush |
| Body-warm (35-38°C) | ★ the perfect window | vinegar opens up, moulds hold tight | touch the bowl before service: warm, not hot |
| Cooled (<25°C) | vinegar goes flat | edible, but tips drop ~15% | 30s of steam rescues it once |
🍚 The thermometer arrives with the rice-paddy unlock; before that, go by feel: the bowl warm like a just-held hand. Floor-88 verdict: rice temperature beats knife work, and it ruined some egos.
