A single extra slice of avocado on your burger costs €0.35, but multiply that by 200 burgers weekly and you're bleeding €3,640 annually. These unplanned garnishes slip past your cost calculations. Most restaurant owners don't realize how dramatically these small additions destroy their margins.
Why extra garnish eats away at your profit
The problem with extra garnish is that it's invisible in your numbers. Your chef thinks: "An extra slice of avocado makes the dish look better." But that avocado costs money that's not included in your cost price calculation.
💡 Example:
Your pasta carbonara has a cost price of €8.50 according to the recipe. But your chef always adds extra:
- Extra grated cheese: €0.40
- Extra slice of pancetta: €0.60
- Parsley garnish: €0.15
Actual cost price: €9.65 (€1.15 more expensive!)
At a selling price of €18.50 (€16.97 excl. VAT), your food cost jumps from 50.1% to 56.8%. That's the difference between profit and loss.
How to calculate the impact of extra garnish
The calculation is straightforward, but you need to include all extra ingredients:
Formula:
New food cost % = (Original cost price + Extra garnish) / Selling price excl. VAT × 100
Add up all extra ingredients. Don't forget the small things like:
- Extra butter on the plate
- Decorative herbs
- Extra sauces
- Larger piece of meat than in the recipe
- Extra vegetables as garnish
The hidden costs on an annual basis
What seems like a few cents per plate quickly becomes a significant amount annually. After managing kitchen operations for nearly a decade, I've seen restaurants lose thousands without realizing it.
💡 Example:
Extra costs of €1.15 per pasta carbonara:
- 15 pastas per day
- 6 days per week open
- 52 weeks per year
Total per year: €5,382 in extra costs
That's almost half a month's revenue flowing away due to extra garnish that's not in the recipe.
How to prevent uncontrolled extra costs
The solution lies in clear agreements and control:
- Recipes are leading: What's in the recipe goes on the plate. No more, no less.
- Portion sizes documented: 25 grams of grated cheese means 25 grams, not "a generous handful".
- Make extras official: If your chef wants extra garnish? Update the recipe and calculate the new cost price.
- Build in controls: Regularly check whether plates match the recipe.
⚠️ Note:
Don't tell your chef to be more economical. Explain that you want the cost price to be accurate. Then he can choose: less garnish or a higher menu price.
Digital recipe management as a solution
With a digital system, you immediately see what each change in a recipe means for your food cost. Add an ingredient? The cost price gets automatically recalculated.
This way you prevent surprises and maintain control of your margins, even when your team gets creative with garnishes.
How to calculate the impact of extra garnish? (step by step)
Inventory all extra ingredients
Stand next to your chef for a service and note everything he adds to the plate that's not in the recipe. Don't forget the small things like extra butter, herbs, or a larger piece of meat.
Calculate the costs per extra ingredient
Look up the purchase price of each extra ingredient and calculate what the portion costs. A slice of tomato at €0.15, extra cheese at €0.40 - add everything together.
Recalculate your food cost percentage
Add the extra costs to your original cost price and divide by your selling price excl. VAT. This way you immediately see how your food cost increases due to the extra garnish.
✨ Pro tip
Weigh your garnish containers before and after each dinner service for 7 consecutive days. If you're using 30% more parsley than your recipes call for, that's costing you roughly €2,400 annually on a busy restaurant.

Frequently asked questions
Do I really have to count every extra parsley leaf?
Yes, because small amounts become large when you multiply them by the number of plates per year. One cent per plate equals €365 annually at 100 plates daily.
What if my chef says extra garnish improves presentation?
Then you need to choose: accept the higher cost price and raise your menu price, or officially update the recipe. But don't let it happen uncontrolled.
How often should I check whether plates match the recipe?
Check your most popular dishes at least once weekly. Review all dishes monthly to catch any creeping changes.
Can't I just build a margin in for extra garnish?
You can, but then you still don't know how much you're actually spending. Better to know exactly what each dish costs and make conscious choices.
What if different chefs use different amounts of garnish?
Then you have a consistency problem. Make clear agreements about portion sizes and ensure everyone follows the same recipe. Consistency is crucial for your cost price.
Should I factor seasonal garnish variations into my recipes?
Absolutely. Create separate recipe versions for seasonal changes or you'll have inaccurate costs half the year. Update costs quarterly for seasonal ingredients.
