Before writing a soylent recipe, it is worth asking a few questions about the intended user (whether this is oneself or somebody else), which set the requirements of the recipe:

  • What are the user's nutritional needs? Things to consider here include:
    • What nutritional standards are going to be applied to determine their nutritional needs?
    • How many calories do they need?
    • How are their calories going to be apportioned between carbs, protein, and fat?
    • Are they male or female?
    • Do they have dietary restrictions such as vegan, kosher, etc.?
    • Do they have special dietary goals, such as weight loss or bodybuilding?
    • What are their food allergies?
  • What is the user's budget?
  • What ingredients are available in the region where the user lives?
  • To what preparation equipment does the user have access to? (Equipment of interest might include a blender, scales of various levels of precision, an ultrasonic processor, etc.)
  • To what extent are good taste and texture important to the user, and what are their aesthetic preferences in this regard?

Once these questions are answered, constructing a soylent recipe consists of answering the following questions about the recipe:

  • What are the ingredients?
  • How much of each ingredient is to be used? Conventionally, this question is answered by specifying the amount to be used in a day's worth of soylent.
  • What is the procedure for preparing the soylent from the ingredients?

The standard procedure for preparing soylent is to measure all of the ingredients, mix them, store the resulting powder, and mix the powder with water near the time of use. But one might follow a different procedure, for example if one is preparing solid soylent, or cooking some of the ingredients; and even if not, there might be fine points to the mixing process which help improve the final product.
