Think of portion standards like sheet music for an orchestra. Without written notes, every musician plays their own version of the song. Your kitchen works the same way - without documented portions, each cook serves their personal interpretation of your dishes.
Why documenting portion standards is crucial
A steak portion of 200 grams costs €6.40. At 250 grams it costs €8.00. Per 50 portions that's a difference of €80 per week - €4,160 per year. And that's just one dish.
⚠️ Watch out:
Without documented standards, your experienced chef might give 200 grams, but your new staff member gives 280 grams. Your food cost can creep up unnoticed from 30% to 42%.
What you need to document for each dish
For each dish you document:
- Main ingredient: exact weight in grams (raw weight before preparation)
- Garnishes: number of pieces or weight per component
- Sauces: volume in ml or weight in grams
- Decoration: specific quantities (3 cherry tomatoes, 2 sprigs of parsley)
- Bread/side dishes: number of slices, weight of potatoes
💡 Example: Salmon with risotto
Portion standard:
- Salmon fillet: 180 grams (raw)
- Risotto: 120 grams (cooked)
- Vegetables: 80 grams
- Sauce: 30 ml
- Garnish: 2 sprigs of dill, 1 lemon slice
Add visual documentation
Text alone doesn't cut it. Add photos of:
- Raw portions: ingredients on a scale
- Plated dishes: what the final result looks like
- Portioning tools: which spoon for which sauce
A photo of 180 grams of salmon on a scale prevents arguments. Everyone sees exactly what the standard is.
Document digitally and make it accessible
Paper recipe books get lost and aren't updated. Digital documentation has advantages:
- Everyone always has the latest version
- Quick search for specific dishes
- Photos and text in one place
- Automatic cost calculation when changes are made
💡 Example: Digital recipe system
In an app you document:
- Exact quantities per ingredient
- Photos of correct portions
- Automatic cost calculation
- Access for your entire team
Change a portion? The cost is recalculated immediately.
Organize training and monitoring
Documentation without training doesn't work. Most kitchen managers discover too late that having perfect documentation means nothing if staff don't understand how to use it. Organize:
- Portioning training: let new staff practice with a scale
- Weekly spot checks: weigh random portions during service
- Feedback conversations: discuss deviations without blame
⚠️ Watch out:
Don't make portion standards a punishment. Focus on consistency and quality, not on 'mistakes'. Staff who feel controlled will resist.
Adjust and update portion standards
Standards aren't set in stone. Adjust when:
- Seasonal changes: smaller tomatoes in winter
- Supplier changes: different packaging sizes
- Guest feedback: portions too large/small according to guests
- Cost development: ingredient becomes too expensive
Always update your documentation and communicate changes to your team. A portion standard that nobody knows about doesn't work.
💡 Example: Cost impact
Increase steak portion from 200g to 220g:
- Extra meat per portion: €0.64
- 50 portions per week: €32
- Per year: €1,664 extra costs
Decision: raise menu price or keep portion the same?
How do you document portion standards? (step by step)
Weigh and measure all components
Take your best-selling dishes. Weigh each ingredient separately: main course, garnish, sauce, decoration. Write everything down in grams or ml. Take photos of the scale with the ingredient on it.
Photograph the plated dish
Take a photo of the complete dish as it goes to the guest. This becomes your reference image. Make sure you have good lighting and photograph from above for clear proportions.
Record in digital system
Enter all data into a digital recipe system. Link photos to the quantities. Make sure your team has access via phone or tablet in the kitchen.
Train your team and monitor
Let new staff practice with the documented portions. Do weekly spot checks by weighing random portions. Discuss deviations and adjust the standard if needed.
✨ Pro tip
Document your 3 highest-cost dishes first within the next 48 hours. These dishes typically account for 60% of your food cost variance, so you'll see immediate impact on your margins.

Frequently asked questions
Do I really need to weigh every ingredient separately?
Yes, especially with expensive ingredients. 10 grams extra salmon per portion costs you €1,600 per year at 50 portions per week. Small deviations have big consequences.
How often should I check portion standards?
Do weekly spot checks during service. Weigh 2-3 random portions of different dishes. This prevents standards from slowly creeping up without you noticing.
What if my chef thinks the standards are too restrictive?
Discuss it openly. Maybe he's right and the portions are too small for your concept. Then adjust the standard, but also raise your menu price to compensate for the cost.
Should I document portion standards for sauces and garnishes too?
Absolutely, especially for expensive garnishes. Three extra cherry tomatoes per plate seems like nothing, but costs €520 per year at 50 covers per day.
How do I handle portion standards during busy service periods?
Train your team to eyeball portions accurately during rush times. But always follow up with spot checks after service to ensure standards weren't compromised.
What's the best way to train new staff on portion standards?
Start them with a scale during prep and slow periods. Let them practice portioning until they can estimate accurately by sight. Visual references help tremendously.
Can I keep portion standards on paper instead of digital?
You can, but digital is more practical. Paper gets lost, isn't updated easily, and you can't attach photos to it. A digital system keeps everything current and accessible.
