Think of a recipe like a car's dashboard – it shows you what's happening under the hood. Your recipe can be both cost control and work instruction simultaneously, keeping your chef consistent while protecting your margins. But most restaurants treat recipes like simple ingredient lists and miss the financial control they offer.
Why use recipes as a control document
Most kitchens have recipes pinned to walls or tucked in binders. They're missing the cost data that matters. Your chef can't see what each portion costs, and you can't verify if your margins make sense.
⚠️ Heads up:
Without cost information on your recipe, your chef might unknowingly give generous portions. An extra spoonful of crème fraîche seems like nothing, but costs you €0.40 per plate.
The dual function of a complete recipe
Smart recipes serve multiple masters at once:
- For the chef: Exact quantities, preparation method, presentation
- For you: Cost per portion, food cost percentage, profit margin
- For the team: Consistency in taste and portion size
What should be on a controlling recipe
A recipe that actually controls contains way more than ingredients:
💡 Example recipe: Pasta Carbonara
Ingredients for 1 portion:
- Spaghetti: 120g (€0.36)
- Bacon: 40g (€1.20)
- Egg: 1 piece (€0.25)
- Parmesan: 25g (€1.40)
- Butter: 10g (€0.12)
Total cost: €3.33
Selling price: €16.50 incl. VAT (€15.14 excl.)
Food cost: 22.0%
Cost control in practice
With costs right on your recipe, you control everything directly:
- Supplier prices: If bacon jumps from €30/kg to €36/kg, you spot the food cost increase instantly
- Portion size: Your chef sees that 25g of parmesan costs €1.40 and won't be heavy-handed
- Profitability: You identify unprofitable dishes immediately
💡 Example cost control:
Your carbonara normally runs 22% food cost. This week it's hitting 26%.
Check: Parmesan jumped from €56/kg to €64/kg. Time to adjust your selling price or find different cheese.
Work instructions everyone understands
Solid recipes eliminate kitchen arguments. No more "a bit of this" or "to taste." Everything's spelled out clearly:
- Exact quantities: 120g pasta, not "a handful"
- Cooking time: "Bake for 3 minutes on medium-high heat"
- Presentation: "Garnish with 3 basil leaves"
- Temperature: "Serve at 65°C"
I've seen restaurants lose EUR 200-400 monthly just from inconsistent portioning – a mistake that compounds quickly across busy service periods.
Digital vs. paper recipes
Paper recipes disappear, get stained, and updating them is painful. Digital versions adapt instantly to price changes.
💡 Digital advantage:
Your supplier raises cream prices. In tools like KitchenNmbrs you adjust the ingredient price once, and all recipes containing cream recalculate automatically.
With paper you hunt down every recipe with cream and recalculate by hand.
Recipes as a team tool
Show your team the costs and they'll start thinking like owners:
- "This garnish costs €2.80 per plate, can we do it cheaper?"
- "If we use 20g less salmon, we save €1.60 per portion"
- "This dish runs 35% food cost, should we raise the price?"
⚠️ Heads up:
Only share cost information with your permanent team. Temporary staff don't need to know what ingredients cost.
How do you create a recipe that controls and instructs?
Gather all ingredients with exact prices
Note each ingredient with precise quantity and current purchase price per unit. Don't forget the small things like oil, salt, spices, and garnish. These costs add up quickly.
Calculate the total cost per portion
Add up all ingredient costs. Also account for any cutting loss (for example with fish or meat). This becomes your base cost per dish.
Add preparation instructions with portion control
Write step-by-step how the dish is made, with exact quantities and times. Also mention how it should be presented, so every plate looks the same.
Calculate food cost and check profitability
Divide the cost by your selling price (excl. VAT) and multiply by 100 for the food cost percentage. Check if this falls within your desired margin (usually 25-35%).
Make the recipe accessible to the team
Make sure your team can easily find and read the recipe while cooking. Digital recipes are handier than paper because they don't get dirty and are always up to date.
✨ Pro tip
Display the food cost percentage prominently at the top of each recipe card – your team immediately sees which dishes generate maximum profit and which require careful preparation. Update these percentages every 6 weeks to stay current.
Calculate this yourself?

Frequently asked questions
Do I need to put costs on every recipe?
Start with your 5 best-selling dishes. If those maintain good food cost, you've solved 80% of your problem. Then expand to the rest.
How often should I update the costs?
Check your main ingredients monthly – meat, fish, specialty products. Basic items like oil and spices can be reviewed quarterly, unless your supplier alerts you to price changes.
What if my chef doesn't stick to the portions exactly?
Show them the numbers and explain why it matters. If 10g extra salmon costs €0.80 per plate, and you sell 50 portions weekly, that's €2,080 annually in extra costs.
What do I do if a dish has too high food cost?
You have three options: raise the selling price, swap ingredients for cheaper alternatives, or reduce portions. First verify the calculation is accurate and includes all costs.
