Cooking chopsticks (菜箸, saibashi) are long chopsticks — typically 30–40 cm — used for cooking rather than eating. Their length keeps hands away from hot oil or boiling liquid while maintaining precision control of individual pieces.
Uses in hot-oil cooking
For tempura and katsu: lower pieces gently into oil using chopsticks; remove and drain with the same. Metal tongs grip more firmly but can break delicate items. Chopsticks also test oil temperature: bamboo tips held in oil bubble gently at 170°C, vigorously at 190°C.
The test-oil technique
Dip chopstick tips into the oil. If no bubbles: below 150°C. Slow bubbles: 160–170°C (tempura range). Fast bubbles: 180–190°C. Rapid vigorous bubbles: above 200°C (too hot for most applications).
