A recipe is a set of instructions for preparing a specific dish or drink. There are several synonyms that can be used instead of the word recipe, including formula, method, procedure, protocol, blueprint, instruction, plan, and prescription. The word formula typically describes a scientific or mathematical formula, but it can also be used to describe a recipe for a chemical or cosmetic product. Method is a common synonym for recipe that refers to the process of preparing or cooking a food or drink. Procedure and protocol both suggest a systematic approach to cooking or following a specific set of instructions. Blueprint and plan are more general terms that can apply to any type of instructions, while prescription implies a medical or dietary restriction.
