くず()

くずこ
noun
arrowroot starch; kudzu starch
1. arrowroot starch; kudzu starch; kuzu powder
A fine white starch extracted from the root of the kudzu plant ((くず)). Used as a thickener in Japanese cooking and as the base for traditional sweets. Prized for the smooth, glossy texture it gives to sauces and desserts.
くず()でとろみをつける。
To thicken with kuzu starch.
くず()(みず)()いてから(なべ)()れる。
Dissolve the kuzu starch in water before adding it to the pot.
(ほん)くず()値段(ねだん)(たか)いが、仕上(しあ)がりの食感(しょっかん)がまったく(ちが)う。
Pure kuzu starch is expensive, but the resulting texture is completely different.

The starch is extracted from the root of (くず) (kudzu/arrowroot vine, Pueraria montana). Written as くず() or 葛粉(くずこ). The くず portion is often written in hiragana.

COMMON COLLOCATIONS:

  • くず()()く: to dissolve kuzu starch (in water)
  • (ほん)くず(): pure kudzu starch (100% kudzu, not blended)
  • くず()でとろみをつける: to thicken with kuzu starch
  • 吉野(よしの)くず: Yoshino kuzu — the most famous producing region

SIMILAR WORDS:

  • 片栗粉(かたくりこ): potato starch — the everyday thickening starch in Japanese kitchens; cheaper and more common
  • コーンスターチ: cornstarch — another thickener, used mainly in Western-style cooking
  • (くず): kudzu (the plant) — the source of the starch

CULTURAL CONTEXT:
くず() is essential for traditional 和菓子(わがし) (Japanese sweets) such as 葛切(くずき)り (kuzu noodles served chilled with brown sugar syrup), 葛餅(くずもち) (kuzu mochi), and 葛湯(くずゆ) (a warm, soothing drink made by dissolving kuzu starch in hot water, traditionally given to people with colds). 吉野(よしの) in 奈良県(ならけん) is the most renowned production area. True (ほん)くず() (pure kudzu starch) is expensive, so many commercial products are blends with 甘薯(かんしょ) (sweet potato) starch.
