Even on the simplest level, pre-preparation is necessary. If you prepare only one short recipe, you must first:
- Assemble your tools.
- Assemble your ingredients.
- Wash, trim, cut, prepare, and measure your raw materials.
- Prepare your equipment (preheat oven, line baking sheets, etc.).
Only then can you begin the actual preparation.
When many items are to be prepared in a commercial kitchen, the situation is much more complex. Dealing with this complexity is the basis of kitchen organization.
