Final answer:
In slicing vegetables for a sub station, an old rule suggested slices 5 diameters wide by 7-8 deep, but newer approaches recommend up to 8 wide and 15 deep, with actual thickness based on dish requirements.
Step-by-step explanation:
When manually slicing vegetables for the sub station, the thickness of each slice can vary based on preference and the type of vegetable being sliced. However, an older "rule of thumb" was to have slices about 5 diameters wide and 7-8 diameters deep. Newer recommendations suggest slices can be thicker, up to 8 diameters wide and 15 diameters deep. While these measurements provide a general guide, consistency and size will depend on the specific requirements of the dish being prepared and the need for uniform cooking times.
