Expensive products with low margins will silently destroy your restaurant's profitability faster than you realize. That €45 wagyu with 15% margin actually earns you less than basic pasta dishes with 35% margins. Three straightforward rules can save your bottom line from this costly mistake.
Rule 1: Set a minimum margin per product
Decide upfront what minimum margin each product must deliver based on its cost price. Higher-priced ingredients need bigger absolute margins to justify their financial risk.
💡 Example margin scale:
- Products up to €10/kg: minimum 30% margin
- Products €10-25/kg: minimum 35% margin
- Products above €25/kg: minimum 40% margin
A wagyu steak at €50/kg must therefore generate at least €83.33 excl. VAT to achieve 40% margin.
This rule guarantees expensive products actually boost your profit instead of draining it. No exceptions for "prestige" items that look impressive but hemorrhage money.
Rule 2: Maximum purchase value per order
Cap how much you spend per order on slow-moving, expensive ingredients. Costly items sitting in storage hit you twice: tied-up cash and spoilage risk.
💡 Example rule:
Maximum 15% of your weekly purchases can go to products above €20/kg.
- Weekly purchases: €2,000
- Maximum for expensive products: €300
- That's for example: 6 kg wagyu (€50/kg)
This prevents excessive capital from getting locked into sluggish inventory. You'll maintain liquidity for high-turnover basics that generate consistent profits. One of the most common blind spots in kitchen management is underestimating how much cash gets trapped in premium ingredients that move slowly.
Rule 3: Mandatory pre-order or reservation
Only sell expensive products through advance orders or with guaranteed minimum reservations. This eliminates the risk of unsold costly ingredients.
💡 Example procedure:
- Wagyu steak: only on Wednesday, minimum 8 reservations
- Fresh truffles: only in October/November, pre-order mandatory
- Fresh oysters: only Friday/Saturday, order by Tuesday
This way you only buy what you're sure to sell.
⚠️ Note:
Communicate this procedure clearly to guests. "Our wagyu is only available on Wednesday, reservation required." Guests appreciate honesty about availability.
Why these rules work
These three rules shield you from the biggest traps of premium ingredients:
- Insufficient margins: Rule 1 ensures every product pulls its weight
- Cash flow problems: Rule 2 maintains healthy liquidity
- Food waste: Rule 3 eliminates unsold expensive inventory
The outcome: you can absolutely feature premium ingredients, but only when they genuinely boost your profitability.
How do you implement these rules? (step by step)
Analyze your current expensive products
Make a list of all ingredients above €15/kg that you use. Calculate the actual food cost percentage and absolute margin per product. Identify which products fall below your desired margin.
Determine your margin scale and budget limit
Set a minimum margin per price class (for example 30%/35%/40%). Calculate what percentage of your weekly purchases can go to expensive products. Start conservatively with 10-15%.
Implement pre-order system
Choose 2-3 expensive products to test with pre-order. Communicate this on your website and to regular guests. Start with one day per week and expand gradually if it works.
✨ Pro tip
Track your top 5 most expensive ingredients weekly for 8 weeks: record purchase amounts, actual sales, and real margins achieved. You'll quickly identify which premium products deserve shelf space and which ones are profit killers.

Frequently asked questions
What if guests are disappointed that expensive products aren't always available?
Honest communication works better than expectations you can't meet. Guests appreciate it when you explain that you only serve fresh, premium products when quality is guaranteed.
How do I calculate the actual margin on an expensive product?
Divide the purchase price by (1 minus desired margin). With €50/kg wagyu and 40% margin: €50 / 0.60 = €83.33 excl. VAT minimum selling price. Check if this is realistic for your guests.
Can I apply these rules to expensive wines too?
Absolutely. Wines above €30 purchase price deserve the same treatment: higher margin requirement, limited budget, and possibly only by order. Wine does have the advantage that it doesn't spoil.
What if I already have too many expensive products in stock?
Work them off through special menus or staff meals, but don't buy new ones until the stock is gone. Learn from this experience and apply your purchasing rules to future orders.
How do you handle seasonal price fluctuations for premium ingredients?
Adjust your margin requirements monthly during peak seasons. Truffle prices can triple in November, so your 40% margin rule might need to become 45% to maintain profitability.
Should these rules apply to signature dishes that define my restaurant?
Even signature dishes must be profitable long-term. If a signature dish uses expensive ingredients, build the true cost into your pricing or find creative substitutions that maintain the dish's character.
