Ever wonder why your food costs creep up despite careful menu planning? Often it's not your regular dishes causing the problem. Specials, seasonal items, and new menu additions can silently drain your profits while flying under your usual monitoring radar.
Why certain dishes demand closer scrutiny
Your regular menu items? You've got those dialed in. But some dish categories can torpedo your margins without warning bells going off.
⚠️ Watch out:
A special you serve 30 times weekly with food costs running 5% too high bleeds €3,900 annually from your bottom line.
Daily specials and rotating dishes
Daily specials are profit killers in disguise. Chefs create them on the fly, eyeball the pricing, and rarely circle back to verify profitability.
💡 Example:
Daily special: Sea bass fillet with risotto for €28.50
- Sea bass: €12.50
- Risotto ingredients: €3.20
- Garnish: €1.80
Total: €17.50 on €26.15 excl. VAT = 67% food cost!
Here's what happens: your chef sees that gorgeous fish and thinks it'll work at the usual markup. But once you factor in prep waste and all the accompaniments, the numbers don't add up.
Seasonal dishes and limited editions
Seasonal ingredients swing wildly in price. That asparagus dish that worked in May becomes a money pit by July - yet most kitchens keep charging the same price.
- Asparagus: Jumps from €8/kg in May to €15/kg in June
- Mussels: Seasonal swings of 30-50%
- Game: Price depends entirely on availability
- Summer fruit: Costs double outside peak season
💡 Example:
Asparagus dish in May vs. June:
- May: €8/kg asparagus = 28% food cost
- June: €15/kg asparagus = 41% food cost
Same dish, same price, but 13% less profit.
New dishes and test phase items
New menu items start with educated guesses about costs. After several weeks, reality hits - but by then guests love the dish and raising prices feels like betrayal.
Common pitfalls with new dishes:
- Portion sizes haven't been standardized yet
- Chef adds extras to impress early customers
- Prep waste gets underestimated
- Side dish costs get overlooked in calculations
Premium dishes and signature items
High-end dishes need extra scrutiny because small percentage errors create big dollar losses. A 5% miscalculation on a €45 entrée hurts more than a 10% error on an €18 dish.
💡 Example:
Impact of 5% excessive food cost:
- On €18 dish: €0.83 loss per serving
- On €45 dish: €2.07 loss per serving
At 20 servings weekly: €864 vs. €2,153 annual difference.
Which categories need extra monitoring
From tracking this across dozens of restaurants, these dish types consistently cause margin problems:
- Daily specials: Verify actual costs weekly
- Seasonal dishes: Adjust pricing with each new delivery
- New dishes: Calculate true costs before menu launch
- Premium items (>€35): Monthly cost reviews
- Fish and meat specials: Most volatile ingredient pricing
- Off-menu regulars: Items for repeat customers that never got properly costed
⚠️ Watch out:
Review these dishes weekly minimum. Waiting a month to fix pricing issues can cost hundreds in lost profit.
Monitoring frequency guidelines
Different dish categories require different check-in schedules:
- Daily: Specials with changing ingredients
- Weekly: Seasonal items and fish/meat features
- Monthly: Premium dishes and signature offerings
- Per delivery: Items with highly volatile ingredient costs
A food cost calculator like KitchenNmbrs can alert you automatically for dishes exceeding target food costs, eliminating manual tracking.
How do you set up extra control? (step by step)
Identify risk dishes
Make a list of all daily specials, seasonal dishes and premium items. These are your control priorities. Check which dishes have fluctuating purchase prices.
Set control frequency
Determine per dish how often you check: daily specials weekly, seasonal dishes with new deliveries, premium items monthly. Note this in your system.
Calculate actual cost price
Add up all ingredients including garnish, sauces and oil. Divide by selling price excl. VAT for food cost percentage. Anything above 35% deserves immediate action.
✨ Pro tip
Track your 3 highest-volume specials and seasonal dishes weekly for the next month. These items likely represent 60% of your margin risk across variable menu categories.

Frequently asked questions
What food cost is acceptable for premium dishes?
Premium dishes above €35 typically run 28-32% food cost. You can afford slightly lower margins since guests pay extra for quality ingredients and presentation. The absolute profit per dish often exceeds your regular menu items.
How often should I check seasonal dishes?
Review seasonal dishes with every supplier delivery or bi-weekly at minimum. Seasonal ingredient prices can spike 50% within a single month, turning profitable dishes into margin killers overnight.
Should I always calculate daily specials in advance?
Absolutely - never wing the pricing on daily specials. Calculate ingredient costs first, then set your selling price based on target food cost percentages. Guessing leads to profit leaks that add up fast.
