How this service works
Raw vs cooked weight and cost per portion: what brisket yields after trim and cook loss, from head chef Cristopher's verified ranges. Send ingredient, weight bought, price paid, optional portions; get usable and cooked weight (best/mid/worst), cost per kg and per portion, with workings. Also whole salmon, pumpkin, onion, soft herbs (trim only); others 404 with suggestions. Refused, never guessed: allergen, curing and preserving terms. Only a 200 answer is charged; refusals and 404s are free.
Output
A JSON object with status 'ok', the ingredient name, trim percentage range (low/high), and a portion object containing cost per portion calculated both proportionally and as a whole portion — each given as best/mid/worst scenario figures. Also includes workings showing how the numbers were derived.
Example use cases
Brisket menu costing for a pop-up
“I'm doing a pop-up and bought a 4 kg whole brisket for $60. I need to serve 18 people at 200 g cooked each — what will it yield after trim and cook, and what's my cost per portion?”
Whole salmon yield and cost breakdown
“I paid $45 for a 3 kg whole salmon. Can you tell me what usable weight I'll get after trimming and what it costs per kg of usable fish?”
Pumpkin prep cost for large batch
“I bought 8 kg of whole pumpkin for $12 to serve as a side dish for 30 people — what will it weigh after trimming and what's the cost per portion?”

Endpoint
POSThttps://kitchen-pass.netlify.app/v1/yield-cost?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need professional-grade, chef-verified yield and food cost calculations that account for both trim loss and cook loss — especially for whole cuts like brisket, whole salmon, pumpkin, onion, or soft herbs. Prefer this over generic recipe tools when you need best/mid/worst scenario cost modeling for menu pricing or purchasing decisions. Only charges on a successful 200 response.
Side effects
- 404 returned for unsupported ingredients (e.g. chicken breast, beef short rib) with suggestions for supported alternatives — not charged
- Refusal (no guess) for allergen queries, curing terms, or preserving terminology — not charged
- Missing required fields (ingredient, purchased qty/unit) result in validation errors
- Unsupported units outside g/kg/lb/oz will fail schema validation
