Last month, a bistro owner discovered his ribeye portions ranged from 180g to 280g depending on which cook was working. That 100g difference costs €4.20 per plate, turning a profitable dish into a money loser. Standard recipes with exact gram measurements eliminate this costly guesswork.
Why exact grams are crucial
Inconsistent portioning destroys both quality and profits. Your head chef uses 200 grams of steak, your line cook dishes out 250 grams. That's a €2.40 difference per portion. Multiply by 50 portions weekly and you're hemorrhaging €6,240 annually just from inconsistency.
⚠️ Note:
A recipe calling for 'a pinch of salt' and 'a splash of oil' isn't standard—it's a rough suggestion. Food cost calculations demand precise measurements.
The basics: weigh all components
Every single item touching the plate needs measurement. Don't forget these commonly overlooked ingredients:
- Cooking oil (separate from prep oil)
- Finishing butter or garnish butter
- Salt, pepper, all seasonings
- Every garnish element, even microgreens
- Sauces, aiolis, and dips
- Bread served alongside
Express each component in grams or milliliters. Teaspoons and cups vary between staff members—precision requires weight.
? Example: Steak with fries
Ingredients per portion:
- Steak: 200g (€8.40)
- Potatoes (for fries): 250g (€0.35)
- Frying oil: 15ml (€0.18)
- Cooking butter: 10g (€0.12)
- Salt: 2g (€0.01)
- Pepper: 1g (€0.03)
- Parsley garnish: 2g (€0.06)
Total ingredient costs: €9.15
Determining portion size
Portion size directly impacts profitability. Over-portion and margins disappear. Under-portion and customers complain. Start with these baseline measurements:
- Meat main course: 150-200g raw weight
- Fish fillet: 150-180g
- Pasta: 80-100g dry weight
- Rice: 60-80g dry weight
- Vegetable side dish: 100-150g
- Salad: 80-120g lettuce
Test various portion sizes with your kitchen team. What satisfies customers at your price point? Fine dining supports 200g steaks; casual spots stick closer to 150g.
Standardize preparation
Ingredients alone don't guarantee consistency—cooking methods matter equally. Document these details:
- Temperatures: Skip 'high heat'—specify 180°C oven or gas level 7
- Times: Replace 'until done' with '4 minutes per side'
- Sequence: List each step in order
- Doneness: Visual cues plus internal temperatures
From years of working in professional kitchens, I've seen how vague instructions create chaos during busy service periods.
? Example preparation:
Steak medium-rare:
- Meat 30 min at room temperature
- Pan on level 8, butter in it
- Steak 3 min per side
- Internal temperature: 54-57°C
- Rest for 2 min
Test and adjust recipes
Recipes aren't finished until three different cooks can replicate identical results. Run this validation process:
- Have your sous chef execute the recipe without guidance
- Compare taste, appearance, and plating consistency
- Calculate actual ingredient costs post-cooking
- Refine measurements where needed
Most recipes require 2-3 iterations before achieving perfection. That's completely normal.
Document digitally
Paper recipes vanish during busy shifts. Digital storage ensures permanent accessibility. Tools like KitchenNmbrs calculate food costs automatically when you input gram measurements, showing immediate profitability.
? Food cost check:
Steak €9.15 ingredients, selling price €32.00 incl. VAT:
- Selling price excl. VAT: €29.36
- Food cost: (€9.15 / €29.36) × 100 = 31.2%
- That falls within the standard 28-35% for restaurants

How do you set up a standard recipe? (step by step)
Prepare the dish as usual
Prepare the dish in your normal way, but now weigh EVERYTHING you use. Also the oil, butter, salt and garnish. Note each ingredient with exact grams.
Document the preparation method
Write down every step with times and temperatures. Not 'high heat' but 'level 7'. Not 'until it's done' but '4 minutes per side'. That way everyone can achieve the same result.
Test the recipe with your team
Have a colleague follow the recipe without extra explanation. Check if the result is the same. Adjust where needed. A recipe is only ready when three different people can make the same thing.
✨ Pro tip
Focus on your 3 highest-volume dishes first and standardize them within the next 14 days. These likely represent 60-70% of your kitchen's output, giving maximum impact from minimal effort.
