Recipes in people's heads are business risk number one. When your chef leaves, the best dishes often disappear with them - including exact food costs. One central system protects this knowledge and ensures you always know what each dish really costs.
Why recipes in people's heads are dangerous
Most kitchen knowledge isn't on paper, but in the heads of your chef and experienced cooks. This seems convenient - no hassle with writing things down - but it's a huge risk.
⚠️ Heads up:
If your chef leaves tomorrow, all recipes, portion sizes, and food costs disappear with them. Your new chef cooks differently, uses different quantities, and suddenly your food cost doesn't add up anymore.
It's not just about the recipes themselves. It's about:
- Exact portion sizes (250g steak or 280g?)
- Food costs per dish
- Which supplier for which product
- Seasonal adjustments and alternatives
- Allergen information per dish
The cost of knowledge loss
What does it cost if recipes disappear? More than you think.
💡 Example:
Your chef leaves. The new chef makes the same dishes, but:
- Steak: 280g instead of 250g (+€2.40 per portion)
- More butter in the sauce (+€0.30 per portion)
- More expensive parmesan brand (+€0.80 per portion)
Extra costs: €3.50 per steak. At 40 steaks per week = €7,280 per year.
And that's just one dish. Add up all your dishes, and you're losing thousands of euros because nobody knows what the original food cost was.
How one system protects you
A central system like KitchenNmbrs prevents this knowledge loss by documenting everything:
- Exact recipes with grams and milliliters
- Food cost per portion calculated automatically
- Supplier information per ingredient
- Allergen information per dish
- Alternative ingredients for seasonal fluctuations
💡 Example:
Restaurant De Eetkamer digitizes all recipes:
- Chef leaves after 3 years
- New chef gets access to all recipes via app
- Food costs stay exactly the same
- No profit leakage from 'new interpretations'
Result: Seamless transition, no extra costs.
More than just preserving recipes
It goes beyond just storing recipes. One system also ensures:
Consistency: Every cook makes the same dish the same way. No surprises in taste or food cost.
Training: New staff learn faster. All information is in one place, always available.
Control: You see immediately if someone deviates from the recipe. Food cost rising? Check if the recipe is being followed.
⚠️ Heads up:
Paper recipes get lost, get dirty in the kitchen, or end up in a drawer at home. Digital means: always available, always clean, always up-to-date.
From chaos to control
Without a system, you have no idea what your dishes really cost. With one central system, you know exactly:
- Which dishes generate the most profit
- Where your profit is leaking
- How supplier price increases affect you
- Which dishes you should promote
💡 Example:
Bistro Het Plein discovers via their system:
- Pasta carbonara: 28% food cost (good)
- Salmon with risotto: 41% food cost (too high)
- Steak: 33% food cost (acceptable)
Action: Adjust salmon recipe or raise price. Savings: €180 per week.
Making the transition
Switching from heads to system takes time, but always pays off. Start with your 5 best-selling dishes. Document:
- Exact ingredients and quantities
- Preparation method step-by-step
- Purchase prices per ingredient
- Allergens per dish
An app like KitchenNmbrs automatically calculates the food cost per portion. You don't have to do the math yourself - the system does it for you.
How do you protect your recipe knowledge? (step by step)
Inventory your current recipes
Make a list of all dishes on your menu. Start with the 10 best-sellers. Ask your chef to write down all recipes with exact grams and milliliters.
Collect all ingredient prices
Note the purchase price and supplier for each ingredient. Also check alternatives for seasonal products. This prevents surprises when prices rise.
Digitize in one system
Put all recipes in one central database. Choose a system that automatically calculates food costs and that your entire team can use. This way knowledge is preserved, even if people leave.
✨ Pro tip
Start by digitizing your signature dish - the dish you're known for. If that recipe disappears, you lose more than money: you lose your identity.
Calculate this yourself?

Frequently asked questions
Does it take a lot of time to enter all recipes?
Start with your 5 best-selling dishes. That takes about 2 hours, but saves you hundreds of euros per month. Gradually add more recipes.
What if my chef doesn't want to help write things down?
Explain that it protects and values his knowledge. If he leaves, his recipes remain. It's recognition of his craftsmanship, not control.
Can't I just use Excel for recipes?
Excel works, but you have to calculate food costs yourself and update them when suppliers change prices. A specialized app does this automatically and is mobile-friendly.
How often do I need to update food costs?
Check your supplier invoices monthly. If an ingredient becomes more than 10% more expensive, update your food cost. This way you stay on top of your actual margins.
What if an ingredient is no longer available?
That's why you always note alternatives. For each main ingredient, you have a backup from another supplier or a replacement product with comparable food cost.
