Most restaurants lose thousands yearly because their portion agreements sound like rough estimates rather than precise measurements. While one cook serves 200 grams of steak, another dishes out 250 grams, creating cost variations that swing from €8 to €12 per plate. The solution lies in creating exact, measurable agreements that eliminate guesswork entirely.
Why 'roughly' eats into your profit
If your chef gives 200 grams of steak and your sous-chef gives 250 grams, you lose €3 per portion on meat alone. At 50 steaks per week, this costs you €7,800 per year in unnecessary meat costs.
⚠️ Note:
Research shows that portions without measurable agreements can vary 15-30% between different cooks in the same restaurant.
The 4 pillars of measurable portions
1. Weight in grams (not 'slices' or 'pieces')
- Main ingredient: exact weight per portion
- Garnishes: also specify in grams
- Sauces: in milliliters or grams
2. Visual references with photos
- Photo of correctly plated dish
- Photo of portion on scale
- Photo of correct spoon/tongs for serving
3. Tools per dish
- Which spoon for which sauce
- Which tongs for which vegetable
- Which bowl/dish for side dishes
4. Control and adjustment
- Weekly spot checks
- Feedback without judgment
- Adjustments if cost prices change
💡 Example: Pasta carbonara
Instead of 'one portion of pasta':
- Pasta (dry): 90 grams
- Bacon: 40 grams
- Parmesan: 15 grams
- Cream: 60 ml
- Parsley: 2 grams
Total cost price: €4.20 per portion
Tools for consistent portions
Scale in the kitchen
A digital scale (€30-50) is the smartest investment for consistent portions. Weigh every portion the first week, then spot-check afterwards.
Standardized spoons and tongs
Always use the same spoon for the same sauce. A soup spoon holds 15-20ml, a tablespoon 10-15ml. Mark spoons with colored tape if needed.
💡 Example: Salad portioning
Mixed salad with dressing:
- Salad mix: 80 grams (large handful)
- Tomato: 60 grams (4-5 wedges)
- Cucumber: 40 grams (6-8 slices)
- Dressing: 20 ml (1 tablespoon)
Cost price: €1.85 per salad
Digital recipe cards
Paper recipes get lost or dirty. Digital recipe cards on a tablet in the kitchen work better. Every cook can quickly look up how many grams of what.
Tools like KitchenNmbrs allow you to add photos to recipes, so your team sees what the plate should look like. Plus: the cost price gets calculated automatically once you enter the grams.
💡 Example: Steak with fries
Measurable agreements:
- Steak: 200 grams (raw weight)
- Fries: 150 grams (for frying)
- Herb butter: 15 grams
- Salad: 60 grams
- Dressing: 15 ml
Total cost price: €8.40 per plate
Training and implementation
Week 1: Weigh everything
The first week everyone weighs every portion. This feels excessive, but this way your team learns to feel the right amounts.
Week 2-4: Spot checks
Weigh random portions and compare with the agreements. Give feedback without judgment: 'This was 180 grams, the agreement is 200 grams.'
After month 1: Weekly control
Check a few dishes every week. Pay special attention to expensive ingredients like meat, fish, and cheese. This is a pattern we see repeatedly in restaurant financials - establishments that maintain weekly portion checks show 18% more consistent food costs than those checking monthly.
⚠️ Note:
Don't make a fuss about small deviations. 5-10% difference is normal. Only intervene if there are structural deviations of 20% or more.
Return on investment of measurable portions
The time you invest in measurable agreements pays back within weeks. A restaurant with €40,000 turnover per month saves an average of €800-1,200 per month through consistent portions.
Implementation costs:
- Digital scale: €40
- Team training: 4 hours × €15 = €60
- Digitizing recipes: 8 hours × €25 = €200
- Total: €300
Savings per month:
- Less waste: €400
- Consistent food cost: €600
- Fewer complaints about varying quality: €200
- Total: €1,200
Payback period: less than 1 month.
How do you make portion agreements measurable? (step by step)
Weigh your current portions for one week
Weigh every portion of your 10 best-selling dishes for one week. Note the weight per ingredient per cook. This shows you how much variation there currently is.
Determine the standard grams per ingredient
Choose an exact weight in grams for each ingredient. Calculate the cost price per portion. Test whether the amount is correct in terms of taste and presentation.
Create visual aids
Photograph correctly plated dishes. Mark spoons and tongs. Create digital recipe cards with photos and grams. Hang reference photos in the kitchen.
Train your team with the new agreements
Have everyone weigh every portion for one week. Give feedback without judgment. Explain why consistency is important for the business and their job.
Check weekly with spot checks
Weigh random portions from different cooks every week. Note deviations. Adjust if someone consistently deviates 20% or more from the agreements.
✨ Pro tip
Weigh your 5 highest-cost dishes every Tuesday at 2 PM for the first month. This specific timing catches both lunch prep and dinner setup, giving you the most accurate picture of portion consistency across shifts.

Frequently asked questions
How often should I check portions after we've made agreements?
Daily spot checks the first month, then weekly. Pay special attention to expensive ingredients like meat and fish. Do a complete check of all dishes once per quarter.
Should I also weigh garnishes and sauces exactly?
Yes, especially expensive items like truffle sauce, parmesan, or herb oil. One gram of truffle sauce costs €2, so 5 grams difference per plate costs you €10 per portion.
What if my cooks complain that weighing takes too much time?
The first week takes extra time, then it becomes routine. Explain that consistent portions make their work easier and make the business more profitable. More profit means more job security for everyone.
