Your profitable dishes aren't selling, and you're watching potential revenue walk out the door. By strategically lowering the price you can make it more popular without losing profit. The art is finding that sweet spot where the dish stays profitable but becomes irresistible to guests.
What is a Puzzle dish?
In menu engineering, a Puzzle dish is:
- High profitability: Low food cost, excellent margin
- Low popularity: Gets ordered rarely
- Hidden potential: Can transform into a Star with smart pricing
💡 Example Puzzle dish:
Beef tenderloin with truffle sauce for €42.00 (incl. 9% VAT)
- Ingredient costs: €12.50
- Selling price excl. VAT: €38.53
- Food cost: 32.4% (fantastic margin)
- Sales: 3 portions per week (terrible)
Problem: Price scares customers away
The minimum price formula
To transform a Puzzle into a Star you need two boundaries:
- Lower bound: Minimum price for your target margin
- Upper bound: Maximum price customers will pay
Minimum price formula:
Minimum selling price excl. VAT = Ingredient costs ÷ (Target food cost % ÷ 100)
⚠️ Warning:
Divide by the food cost percentage - don't multiply! This trips up even experienced managers.
Practical calculation
Let's work through the beef tenderloin example with different scenarios:
💡 Scenario calculation:
Ingredient costs: €12.50
At 35% food cost:
- €12.50 ÷ 0.35 = €35.71 excl. VAT
- €35.71 × 1.09 = €38.92 incl. VAT
At 33% food cost:
- €12.50 ÷ 0.33 = €37.88 excl. VAT
- €37.88 × 1.09 = €41.29 incl. VAT
Market research and competition
Research what comparable dishes cost at competitors:
- Survey 3-5 similar restaurants in your area
- Compare portion sizes and quality levels
- Identify the acceptable price range for this dish type
If competitors sell beef tenderloin for €35-40, then €42 prices you out of the market.
Test the new price
Roll out the adjusted price and track performance:
- Week 1-2: Establish baseline sales at new price
- Week 3-4: Train staff to promote the dish
- Month 2: Assess whether it's achieved Star status
💡 Star criteria:
- Sales jump to 8+ portions per week
- Food cost remains below 35%
- Customers reorder it regularly
- Staff confidently recommends it
Based on real restaurant P&L data, successful Puzzle-to-Star transformations typically see a 150-200% increase in weekly sales volume within 6 weeks of price optimization.
Alternative approach: add value
Sometimes adding value beats lowering the price:
- Upgrade side dishes with minimal cost impact
- Enhanced presentation or garnish
- Compelling menu descriptions
This preserves your margin while making the dish more appealing. You could use tools like KitchenNmbrs to model different scenarios and find the optimal balance.
How do you calculate the minimum price for a Puzzle dish?
Determine your ingredient costs exactly
Add up all costs: main ingredient, side dishes, sauces, garnish and oil. Don't forget any single component that goes on the plate.
Choose your maximum food cost percentage
For fine dining usually 28-33%, for casual dining 30-35%. The higher your food cost, the lower your minimum price can be.
Calculate the minimum selling price
Divide ingredient costs by desired food cost percentage. Multiply by 1.09 for VAT. This is your absolute lower limit.
Check competitor prices
Research what comparable dishes cost at 3-5 competitors. Your minimum price must fall within the market range.
Test and monitor sales figures
Implement the new price and track sales for 4-6 weeks. A true Star sells at least 2x as much as before.
✨ Pro tip
Track your beef tenderloin's total weekly profit for 8 weeks after the price change. Even if individual portions earn less, higher volume often delivers 40-60% more total profit per week.

Frequently asked questions
What if my minimum price is still too high for the market?
Then you need to reduce ingredient costs by finding cheaper alternatives, serving smaller portions, or removing the dish entirely. Sometimes a dish simply can't work in your market at any profitable price point.
How much must sales increase to go from Puzzle to Star?
A Star must rank in the top 30% of your menu's best-sellers. This usually means doubling or tripling your current sales volume, depending on your menu mix.
Should I adjust all Puzzle dishes simultaneously?
Never test multiple dishes at once - you won't know which changes work. Focus on one dish at a time and learn from each adjustment before moving to the next.
