- Clean and dry knives immediately after use.
4.4 Efficiency and Workflow
- Arrange mise en place to minimize movement.
- Practice repetitive cuts to develop speed and muscle memory.
5. The Science of Cutting
5.1 Enzymatic Reactions
- Cutting increases surface area, accelerating reactions such as:
- Browning (Maillard reaction) in onions or meats.
- Oxidation in fruits and vegetables.
5.2 Texture Influence
- Thickness of cuts affects mouthfeel:
- Thin slices of cucumber remain crisp in salads.
- Thick-cut potatoes yield soft interiors after roasting.
5.3 Heat Transfer and Cooking Time
