Standardized portions turn chaotic kitchens into profit machines. Every gram matters - one chef serves 200g pasta while another dishes out 280g, creating wildly different costs and guest experiences. Setting exact portion standards per recipe eliminates this costly guesswork.
Why setting portion standards is essential
Without fixed portion standards, your kitchen operates in complete chaos. One chef serves 200 grams of pasta, another 280 grams. The result: inconsistent quality and unpredictable costs.
- Consistent guest experience - every plate looks the same
- Predictable food cost per dish
- Better inventory planning and purchasing
- Easier to train new staff members
⚠️ Note:
A difference of 50 grams of meat per portion can cost you €3,000+ per year at an average restaurant. Portion standards aren't a detail, they're direct money.
How food cost software manages portion standards
Modern systems let you set exactly how much of each ingredient goes into one portion per recipe. The software automatically calculates the cost price based on your purchasing prices.
What you can set:
- Main ingredients (meat, fish, pasta) in grams
- Garnishes and vegetables in grams or pieces
- Sauces in milliliters or grams
- Oils, butter and spices in grams
- Everything that goes on the plate
💡 Example: Pasta Carbonara
Here's how you set the portion standard digitally:
- Pasta (tagliatelle): 120 grams
- Bacon (guanciale): 40 grams
- Egg (yolk): 2 pieces
- Parmesan: 25 grams
- Pepper: 2 grams
System automatically calculates: cost price €4.20 per portion
Different portion standards for different times
Many restaurants have different portion sizes for lunch and dinner, or special portions for children. Digital recipe management lets you create multiple variants of the same dish.
- Lunch portion: 80% of the dinner portion
- Dinner portion: Standard portion
- Kids menu: 60% of the dinner portion
Each gets its own cost price calculation and food cost percentage.
From portion standard to practice
A digital portion standard is only valuable if your kitchen team uses it. The transition from "by feel" to "by standard" requires careful implementation. I've seen restaurants lose EUR 200-400 monthly simply because they set standards but never trained staff to follow them consistently.
💡 Example: Steak implementation
Week 1: Measure all steaks going out - average 240 grams
Set standard: 220 grams per steak
Week 2-4: Train team with scale
Result: 20 grams less per steak = €2,400 savings per year
Update portion standards as prices change
Your supplier raises prices, you've got choices: accept higher cost price or serve smaller portions. Recipe management software shows you immediately what both options mean for your margin.
- Scenario 1: Raise price on menu
- Scenario 2: Reduce portion by 10%
- Scenario 3: Find cheaper ingredient
The system calculates all scenarios, so you can make an informed decision.
How do you set portion standards in KitchenNmbrs? (step by step)
Create a new recipe
Go to 'Recipes' in the app and click 'New recipe'. Enter the name of the dish and choose the number of portions you want to make (usually 1 portion for accuracy).
Add ingredients with exact quantities
Add each ingredient from your ingredient library. Enter the exact quantity for each ingredient (grams, milliliters, pieces). Don't forget garnishes, spices or oils that go on the plate.
Check and save
KitchenNmbrs automatically calculates the cost price per portion. Check that all quantities match what you use in the kitchen. Save the recipe - your portion standard is now set and the cost price will automatically update when prices change.
✨ Pro tip
Track your top 8 dishes for exactly 5 days before setting any standards. You'll discover portion variations you never knew existed - and save hundreds monthly by fixing them.
Calculate this yourself?

Frequently asked questions
Can I have different portion standards for lunch and dinner?
Yes, just create two separate recipes: 'Pasta Carbonara Lunch' and 'Pasta Carbonara Dinner' with different quantities. The system calculates the cost price for both versions.
What if my chef doesn't follow the portions exactly?
Start by measuring what's going out now. Set that as the standard and gradually train toward the desired portion size. Rome wasn't built in a day.
Do I need to weigh everything in the kitchen?
At first yes, to develop a feel for the right portions. After a few weeks, most cooks know the portions by heart. Spot-checking remains useful.
How often should I adjust portion standards?
Only if you deliberately choose different portion sizes or if ingredient prices rise sharply. The standard itself doesn't need to change often - that's the whole point of standardization.
What if I use seasonal ingredients?
Create seasonal variants of the same dish. 'Spring Risotto' with asparagus and 'Fall Risotto' with pumpkin. Both get their own portion standard and cost price calculation.
Should I include garnishes and micro-ingredients in portion standards?
Absolutely - those 5 grams of truffle oil or 3 cherry tomatoes add up fast. Track everything that touches the plate, no matter how small it seems.
