Seasonal ingredients have a short shelf life but offer the best flavor and margins. The problem: you need to act quickly and plan well to prevent waste. Smart kitchen planning helps you maximize seasonal products without losing money to spoiled ingredients.
Why seasonal planning is crucial for your margin
Seasonal ingredients are often 30-50% cheaper than their frozen alternatives. White asparagus costs €8/kg in May, €24/kg in January. The problem: fresh asparagus deteriorates after 3-4 days.
💡 Example:
You buy 10 kg fresh strawberries for €3/kg = €30 total
- Day 1-2: Perfect quality, sell for €1.50/portion
- Day 3: Slightly softer, still usable for desserts
- Day 4: Only suitable for jam or smoothies
- Day 5+: Thrown away = €30 loss
Without planning: 40% waste = €12 loss
The 3-day rule for seasonal purchasing
Never buy more seasonal ingredients than you can process in 3 days. This prevents waste and keeps your inventory costs low.
- Day 1: Use for signature dishes (highest margin)
- Day 2: Process into daily specials
- Day 3: Last chance - make soup, sauce or appetizer
⚠️ Note:
Always account for 10-15% natural loss with seasonal products. A kilogram of strawberries yields approximately 850 grams of usable product.
Menu engineering with seasonal products
Plan your menu around the shelf life of seasonal ingredients. Create a cascade system:
- Main course: Fresh asparagus with hollandaise (day 1-2)
- Side dish: Asparagus soup (day 2-3)
- Amuse: Asparagus mousse (day 3)
This way you use every ingredient optimally and minimize waste.
💡 Example cascade planning:
15 kg fresh peas (€4/kg = €60 purchase)
- Day 1: 8 kg for pea risotto (€16/portion)
- Day 2: 5 kg for pea soup (€8.50/bowl)
- Day 3: 2 kg for pea hummus (€6/appetizer)
Waste: 0 kg - Optimal utilization
Inventory rotation and FIFO system
With seasonal products, FIFO (First In, First Out) is critical. Label everything with purchase dates and use the oldest first.
Create a simple system:
- White stickers = day 1 (premium use)
- Yellow stickers = day 2 (daily specials)
- Red stickers = day 3 (last chance)
Supplier agreements for flexibility
Make agreements with suppliers about smaller, more frequent deliveries during seasons. Better 3 times per week 5 kg than once per week 15 kg.
💡 Example supplier deal:
Normal agreement: 20 kg strawberries per week = €60
Seasonal agreement: 7 kg every 2 days = €21 per delivery
Benefit: Always fresh quality, less waste
Cost price calculation with seasonal variation
Recalculate your cost price per season. A strawberry dessert costs €2.80 in ingredients in June, €6.40 in December.
Seasonal cost price formula:
Cost price = (Seasonal ingredient price × quantity) + fixed costs + waste percentage
⚠️ Note:
Don't update your menu card every week, but calculate internally with seasonal prices. This way you know which dishes are temporarily less profitable.
Digital planning and tracking
Keep track of which seasonal products are best when and what they cost. This helps you make better purchasing decisions next year.
An app like KitchenNmbrs helps you track seasonal prices and automatically adjust your cost prices when ingredient prices change.
How do you plan seasonal purchasing optimally?
Calculate your 3-day consumption
Add up how much of each seasonal product you use in 3 days. Never buy more than this amount. Account for 10-15% natural loss.
Create a cascade menu
Plan 3 different preparations per seasonal product: premium (day 1), daily special (day 2), leftover processing (day 3). This way you use everything optimally.
Label and rotate systematically
Use colored stickers to track purchase dates. White = day 1, yellow = day 2, red = last chance. Always use the oldest first.
✨ Pro tip
Take photos of seasonal products on day 1, 2 and 3. This way you learn exactly when to switch to different preparations.
Calculate this yourself?
In the KitchenNmbrs app you can do this in just a few clicks. 7 days free, no credit card.

Frequently asked questions
How much waste is normal with seasonal products?
Between 10-20% waste is normal with seasonal products due to natural spoilage. Above 25% indicates poor planning or excessive purchasing.
Should I adjust my menu price per season?
Not necessarily your menu card, but calculate internally with seasonal prices. This way you know which dishes are temporarily less profitable and can focus less on them.
How often should I purchase seasonal products?
For optimal freshness: every 2-3 days in small quantities. This takes more time but prevents waste and keeps quality high.
What if I've purchased too much seasonal product?
Process immediately into shelf-stable products: make jam, soup, sauces or freeze in portions. Better a lower margin than total loss.
How do I calculate the actual cost price of seasonal products?
Seasonal price + 15% waste + processing time. So €4/kg strawberries becomes €4.60/kg actual cost price due to natural loss.
