How this service works
Scale a recipe from 4 to 50 servings (serves), double or halve it, with head chef Cristopher's verified rules. Each line says why: straight maths, fixed ratio (garlic, onion, ginger, thickeners) or start low and taste up (salt in a soup), plus scaling-up tips: roasting, frying, stir-fry, braises, cakes, bread. Units: g, kg, ml, l, tsp, tbsp, lb, oz, cups. Refused, never guessed: allergen-free, curing, pickling, preserving and fermenting recipes. Only a 200 answer is charged; refusals are free.
Output
Returns a JSON object containing a per-ingredient lines array, each with the original input, the scaled display quantity, and the approach used (straight math, fixed ratio, or start-low). Also returns the overall scaling factor and a provenance label confirming chef verification. Includes large-batch cooking tips where relevant to the method.
Example use cases
Catering a large office lunch
“I need to scale up my roast chicken recipe from 4 portions to 50 portions for a work event — can you tell me how much of each ingredient I need, especially for things like garlic and salt where I shouldn't just multiply blindly?”
Halving a bakery cake recipe
“I only want to make half the batch of this chocolate cake recipe that normally serves 12 — scale it down to 6 servings and let me know if anything like baking powder needs special treatment rather than just being halved.”
Meal-prep scaling for a weekly cook
“I want to scale this tomato pasta sauce recipe from 4 servings to 20 servings for my weekly meal prep — the ingredients are 400g crushed tomatoes, 4 cloves garlic, 1 onion, 10g salt, 2 tbsp olive oil, 1 tsp dried oregano. Use metric cups please.”
Technical details
Endpoint
POSThttps://kitchen-pass.netlify.app/v1/scale?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need chef-verified, ingredient-aware recipe scaling that applies different rules per ingredient type (fixed-ratio aromatics, taste-sensitive salt, straight-math proteins) rather than naive multiplication. Ideal when scaling to large portions (20–50 servings) where cooking method advice (roasting, braises, baking) matters. Not suitable for allergen-free adaptations, curing, pickling, preserving, or fermenting recipes.
Side effects
- Recipe involves allergen-free, curing, pickling, preserving, or fermenting — endpoint refuses without charge
- Target portion count outside supported range (4–50 servings) — likely refusal or error
- Unrecognized ingredient or ambiguous unit — may return partial result or refusal
- Malformed recipe input (missing qty or item fields) — validation error
- Invalid cupSize enum value — schema validation error
