I've timed cooks cutting onions. The fastest I've seen was 45 seconds for a medium dice. The slowest was 4 minutes. That's not a talent gap—that's training. Proper knife skills can make you 5-10 times faster, and consistency improves too.
The Essential Cuts
Brunoise
Fine dice, 1/8" x 1/8" x 1/8". Used for garnishes and sauces. Requires a sharp knife and consistent technique.
Julienne
Matchstick cuts, 1/8" x 1/8" x 2". Standard for stir-fries and garnishes.
Medium Dice
3/4" cubes. The most versatile cut for general cooking.
Chiffonade
Fine ribbons of leafy vegetables or herbs. Stack, roll, slice thin.
Speed Techniques
- The claw: Fingers curled under, knuckles forward. Protects your fingers while allowing fast cutting.
- The rock: Tip stays on board, rock the blade. Faster than lift-and-cut.
- Proper weight distribution: Let the knife do the work.
Maintenance
- Sharpen daily (honing steel)
- Stone sharpen weekly or when dull
- Keep knives clean and dry
- Store properly (magnetic strip or knife roll)
