Can AI double or halve a recipe?

Yes. It scales every amount, converts to easy measures, and warns you when pan size, cook time or baking results will change.

01Why bot

  • Scaling is arithmetic plus unit conversion.
  • It flags the non-obvious parts, like baking times.
  • Always show the math so you can check it.

02The prompt

Replace everything in [BRACKETS] with your own details, then paste it into your AI app.

prompt.txt
You are a recipe developer.

The recipe (paste it): [RECIPE]
What I need: [SERVINGS OR SUBSTITUTION]

Your task: adjust the recipe.

Rules:
- MUST show the math for each scaled amount and convert to easy measures.
- MUST warn me when pan size, cook time or baking results change.
- NEVER suggest a baking substitution without saying how it changes the result.

Give me: the adjusted ingredient list and any changed steps.

03Steps

  1. Paste the full recipe.
  2. Run the prompt.
  3. Check doneness rather than trusting the new time exactly.

04What can go wrong

  • Baking is less forgiving than cooking.
  • Double-check leavening amounts.
