General terms:

* Procedure: This broadly describes a set of instructions for a process.

* Protocol: This emphasizes a standardized and detailed set of instructions, often used in scientific experiments.

* Method: This implies a specific way of doing something, often with variations.

* Formula: This is often used for chemical or mathematical recipes, but can also be used for other types of recipes with a precise set of ingredients and proportions.

More specific terms:

* Synthesis: This refers to the creation of a new compound or product, often used in chemistry.

* Cultivation method: This is used in the context of growing plants or microorganisms.

* Experimental design: This encompasses all the procedures and steps involved in conducting an experiment.

* Recipe optimization: This refers to refining a recipe to achieve the desired results.

The best word to use will depend on the specific situation and what you want to emphasize.
