A high-end steakhouse discovered their signature dishes were costing €3.20 more than calculated - all because they weren't tracking sub-recipe costs properly. Sub-recipes are recipe components like sauces, marinades, and garnishes that you use across multiple dishes. Without proper tracking, your actual food costs can spiral beyond your projections.
What are sub-recipes and why are they crucial?
A sub-recipe is a dish component you prepare separately and reuse across multiple menu items. Common examples include:
- Signature sauces (hollandaise, jus, house pesto)
- Marinades and custom dressings
- Specialty sides (compound butters, garnish mixes)
- Foundation preparations (stocks, tapenade, reductions)
The costly oversight: restaurants often guesstimate these costs or ignore them entirely. Your food cost calculations become dangerously inaccurate.
💡 Example:
Your ribeye costs €8.50 for the protein. But you're also serving:
- House herb butter: €0.65
- Red wine jus: €1.20
- Roasted vegetable medley: €1.85
True cost: €12.20 (not €8.50!)
How sub-recipes work in your cost calculations
The system automatically integrates sub-recipe costs into your main dishes. Here's the process:
Step 1: Build your sub-recipe foundation
Navigate to 'Recipes' → 'New recipe' and input every ingredient for your sub-recipe. Take hollandaise sauce:
- Egg yolks: 3 pieces
- Unsalted butter: 125g
- Fresh lemon juice: 15ml
- White pepper and kosher salt
Step 2: Link sub-recipes to main dishes
For your main course (like asparagus benedict), add 'Hollandaise sauce' under ingredients and select your created sub-recipe. Specify the exact portion size you'll use.
⚠️ Note:
Portion accuracy is everything. One liter of hollandaise serving 8 guests = 125ml per portion, not the full liter cost.
Critical sub-recipe mistakes to avoid
Based on real restaurant P&L data, these errors consistently inflate food costs:
Mistake 1: Incorrect portion calculations
You batch 1 liter of peppercorn sauce for 10 servings but calculate using the entire liter cost per plate. Always verify: what's the actual ml/gram usage per serving?
Mistake 2: Ingredient double-counting
Adding butter to both your main dish and your herb butter sub-recipe means you're counting butter twice. Choose one method: either the sub-recipe or individual ingredients.
💡 Example calculation:
Linguine carbonara with house-made sauce:
- Fresh linguine: €0.85
- Sub-recipe carbonara sauce (120ml): €2.40
- Aged Parmesan (extra): €1.10
- Fresh parsley: €0.15
Total cost: €4.50 per portion
Sub-recipe advantages for cost control
Universal reusability
Build your hollandaise once and deploy it across asparagus dishes, eggs benedict, and fish preparations. Price updates happen once and cascade automatically to all linked dishes.
Precision costing
End the guesswork around sauce costs. You'll see exactly how each component impacts your overall food cost percentage.
Operational efficiency
No more re-entering sauce ingredients for every dish. Select the sub-recipe and you're finished.
💡 Real-world example:
Restaurant De Smederij uses their truffle aioli across 5 signature dishes. Creating it as a sub-recipe delivered:
- 20 minutes weekly saved on data entry
- Consistent accurate costing
- Instant visibility on price impact from truffle fluctuations
Sub-recipe implementation strategy
Deploy sub-recipes for:
- Signature sauces: Hollandaise, béarnaise, house pesto, specialty aioli
- Protein marinades: For meats or seafood appearing in multiple preparations
- Complex accompaniments: Compound butters, artisanal tapenades, seasonal chutneys
- Foundation elements: House stocks, reductions, demi-glace
Skip sub-recipes for:
- Basic seasonings (salt, pepper, standard oils)
- One-off preparations you won't repeat
- Items you purchase pre-made
Add sub-recipes in 3 steps
Create the sub-recipe
Go to 'Recipes' → 'New recipe'. Fill in all ingredients of your sub-recipe with exact quantities. Give it a clear name like 'Hollandaise sauce' or 'Herb butter'.
Calculate the portion size
Determine how much of your sub-recipe you use per portion of main dish. For example: 1 liter of hollandaise for 8 portions = 125ml per portion. This becomes your standard quantity.
Link to main dish
For your main dish, add your sub-recipe under ingredients. Select it from the list and fill in the quantity per portion. KitchenNmbrs automatically calculates the costs.
✨ Pro tip
Track your 8 most-used sub-recipes weekly for portion accuracy - even a 10ml variance in sauce usage can shift your food cost by 0.5% across high-volume items. Consistency drives profitability.

Frequently asked questions
Can I use a sub-recipe in multiple main dishes?
Yes, that's the core benefit. Create your hollandaise once and use it in asparagus, eggs benedict and fish preparations. Price changes require just one update.
How do I determine the correct sub-recipe portion per serving?
Measure it during actual preparation. Make your sauce, divide it across your planned portions, then weigh or measure one serving. This becomes your standard quantity.
What if I use sub-recipe ingredients separately in the main dish too?
Pick one approach: either use the sub-recipe or add ingredients individually. Double-counting will inflate your costs. Sub-recipes usually provide better consistency.
Can I create sub-recipes for garnish and plating elements?
Absolutely. Herb butters, microgreen mixes, or signature oil drizzles work perfectly as sub-recipes. You'll capture every cost and maintain consistency.
How do I update sub-recipe prices when ingredient costs change?
Adjust the ingredient prices within your sub-recipe. The system automatically recalculates all main dishes using that sub-recipe, showing immediate cost impact.
Should I create sub-recipes for seasonal menu items?
Yes, especially if you rotate seasonal items annually. Your spring pea puree or autumn squash reduction can be reactivated next season with current pricing. It saves significant setup time.
