Ever wondered why your food costs seem to fluctuate wildly even though you're buying the same ingredients? One chef calculates €12 per kilo beef, another uses €14. But the chaos in your food costs comes from everyone working with their own version of the truth.
Why personal lists are dangerous
Every chef has their own way of working. One keeps prices in a notebook, another just remembers them. But nobody works with the same numbers.
⚠️ Watch out:
If your head chef calculates €18 per kilo salmon and your sous chef uses €22, the same dish can have a 25% difference in food cost. That's the difference between profit and loss.
The costs of different truths
When everyone uses their own numbers, these problems pop up:
- Inconsistent portions: Chef A serves 200g steak, chef B serves 250g
- Different prices: Old purchase prices mixed with new prices
- Wrong food costs: You don't know what dishes actually cost
- Quality differences: The dish tastes different every service
💡 Example:
Your pasta carbonara is made by 3 chefs:
- Chef A: €6.20 ingredient costs (own list)
- Chef B: €7.80 ingredient costs (different portions)
- Chef C: €5.40 ingredient costs (old prices)
Difference: €2.40 per plate. At 100 portions per week = €12,480 per year in uncertainty.
Creating one central truth
The solution is straightforward: one system where all current information lives. No more individual lists.
What needs to be centralized:
- Current purchase prices per ingredient
- Exact recipes with portion sizes
- Food cost per dish
- Supplier information
- Allergen information
💡 Example:
Instead of 5 different lists, you work with one central database:
- Beef entrecôte: €24.50/kg (last invoice March 15)
- Entrecôte portion: 220g = €5.39
- Side dishes: €2.10
- Garnish: €0.85
Total food cost: €8.34 - the same for everyone
Digital vs. paper system
Paper lists get lost, don't get updated, and nobody knows which version is correct. A digital system fixes this mess.
Benefits of going digital:
- Everyone sees the same current prices
- Updates are immediately visible to everyone
- No lost lists
- Automatic food cost calculation
- History of price changes
⚠️ Watch out:
A digital system only works if your team actually uses it. Make sure to provide proper training and make it part of the daily routine.
Training your team on one system
The best system doesn't work if your team won't use it. From tracking this across dozens of restaurants, training is what separates success from failure.
Steps for successful implementation:
- Explain why it matters (not just how)
- Train all chefs at the same time
- Make one person responsible for updates
- Check weekly that everyone's using the system
- Ban personal lists from the implementation date
💡 Example:
Successful implementation at a bistro with 4 chefs:
- Week 1: Enter all recipes and prices
- Week 2: 2-hour training for all chefs
- Week 3: Head chef checks daily usage
- Week 4: All old lists thrown away
Result: 15% more consistency in food costs within 1 month

How do you create one central truth? (step by step)
Gather all current lists and recipes
Collect all individual lists, notebooks, and recipes. Check which prices are current by comparing them with your latest invoices. Throw away outdated information.
Choose one digital system for your whole team
Select an app or system that everyone can access. Enter all current recipes, ingredients, and prices. Make sure all team members have access with their own account.
Train your team and ban personal lists
Organize training for all chefs. Explain why consistency is important and how the system works. Make it clear that personal lists are now forbidden.

Frequently asked questions
What if my chefs don't want to use an app?
Explain what it gets them: no more hassle figuring out which price is correct, fewer mistakes, and dishes that always taste the same. Focus on the benefit for them, not the technology.
How often should I update prices in the system?
Update prices immediately when you receive a new invoice from your supplier. Make one person responsible for these updates so it doesn't get forgotten.
What if a chef secretly uses their own list anyway?
Check weekly that everyone's using the system. If you notice food costs are off, have a conversation. Explain again why consistency is crucial for profitability.
Can't I just share one Excel file?
Excel works, but then everyone needs access to the same version. An app is more convenient because updates are automatically visible to everyone, even on phones in the kitchen.
What if my sous chef is better at food costs than I am?
Perfect! Let them enter and maintain the prices. It doesn't matter who does it, what matters is that everyone works with the same current information.
How do I handle seasonal price fluctuations across multiple suppliers?
Set up supplier codes in your system and update prices monthly for seasonal items. Track which supplier offers the best value for each ingredient during different seasons.
